In 2026, industrial food crushers operating in the EU must comply with the Machinery Directive (2006/42/EC) and its successor framework, the Machinery Regulation (EU) 2023/1230, along with food-contact material regulations, hygiene design standards such as EN 1672-2, and workplace safety rules covering noise and vibration exposure. These requirements apply to any manufacturer, importer, or facility operator placing food crushing equipment into service within the European Economic Area. The sections below unpack each regulatory layer in practical detail.
Which regulations govern industrial food crushers in the EU?
PALMIA® industrial bone crushers
PALMIA® industrial bone crushers and all other industrial food crushers in the EU are governed primarily by the Machinery Regulation (EU) 2023/1230, which replaces the Machinery Directive 2006/42/EC and becomes fully applicable in 2027, meaning equipment placed on the market today must still satisfy the Directive while manufacturers prepare for the Regulation’s stricter digital and safety requirements. Alongside this, food processing equipment must comply with Regulation (EC) No 1935/2004 on food-contact materials, ensuring no harmful substances migrate from machine components into the product.
Additional layers of legislation apply depending on the specific application. Where food crushers handle animal by-products such as bones or slaughterhouse waste, Regulation (EC) No 1069/2009 on animal by-products sets processing and hygiene conditions. Workplace health and safety directives, including the Physical Agents Directive (2003/10/EC) for noise and Directive 2002/44/EC for vibration, also bind facility operators rather than manufacturers directly but shape the technical specifications buyers should demand from their equipment suppliers.

Harmonised European standards sit beneath this legislative framework and provide the practical technical detail. Standards such as EN ISO 12100 for general machinery risk assessment and EN 1672-2 for food machinery hygiene design translate the broad legal requirements into specific engineering criteria. Compliance with these harmonised standards creates a presumption of conformity with the underlying legislation, which is why most reputable manufacturers design to them as a baseline.
What does CE marking require for food crushing equipment?
CE marking for food crushing equipment requires the manufacturer to complete a conformity assessment demonstrating the machine meets all applicable essential health and safety requirements under the Machinery Directive (or Regulation from 2027 onward), compile a technical file documenting design, risk assessment, and test results, issue an EU Declaration of Conformity, and affix the CE mark before the equipment is placed on the market or put into service.
For most industrial food crushers, the conformity assessment can be conducted by the manufacturer itself through internal production control, provided the machine does not fall into the Directive’s Annex IV category of particularly hazardous machinery. The technical file must remain accessible to market surveillance authorities for at least ten years and must include a full risk assessment carried out in accordance with EN ISO 12100, covering mechanical hazards such as entrapment in the crusher roll, electrical hazards, and hygiene-related risks.
The Declaration of Conformity must identify the specific directives and harmonised standards applied, the manufacturer’s name and address, and the authorised signatory. Buyers should request this document before installation and verify that the standards listed are current versions. A CE mark applied against an outdated standard version does not necessarily guarantee compliance with today’s requirements, particularly as harmonised standard lists are updated periodically by the European Commission.
What hygiene design standards apply to food crusher components?
The primary hygiene design standard for food crusher components is EN 1672-2, which defines hygiene requirements for food processing machinery including surface finish specifications, drainage design, material compatibility, and accessibility for cleaning. Components in the food zone must be made from materials that are non-toxic, non-absorbent, corrosion-resistant, and capable of withstanding the cleaning agents used in the facility.
Surface and material requirements
All surfaces in direct contact with food must be smooth, free of crevices, and finished to a roughness that prevents bacterial adhesion. Stainless steel grades such as 304 and 316 are the standard choice for food-zone components because they resist corrosion from both food acids and alkaline cleaning chemicals. Welds must be continuous and ground flush, since gaps and rough weld beads create harbourage points for pathogens that cannot be reached during routine cleaning-in-place procedures.
We manufacture our PALMIA® bone crushers primarily from stainless steel with hygiene in mind, ensuring that cleaning is straightforward and that the machine can be thoroughly washed down between production runs. This design philosophy directly addresses the EN 1672-2 requirement that machinery be cleanable without special tools or disassembly of sealed components.
Drainage and accessibility requirements
EN 1672-2 also requires that food machinery be designed so that liquids drain away completely under gravity, preventing pooling that would allow microbial growth. Horizontal surfaces in the food zone should be avoided or angled to promote drainage. Equally important is accessibility: all food-contact surfaces must be reachable for manual cleaning or designed for effective clean-in-place systems. Enclosed drives, sealed bearings with labyrinth seals, and removable panels all contribute to meeting this requirement while protecting mechanical components from ingress of water and product residue.
How do noise and vibration limits affect food crusher compliance?
Noise and vibration limits affect food crusher compliance by setting upper thresholds that determine whether additional engineering controls, personal protective equipment, or operational restrictions are required in the facility where the equipment operates. Under the Physical Agents (Noise) Directive, the daily exposure action value is 80 dB(A), with an upper action value of 85 dB(A), above which employers must implement noise reduction measures. For vibration, the hand-arm daily exposure action value is 2.5 m/s².
Manufacturers are required under the Machinery Directive to declare the noise emission of their equipment in the technical documentation and, where it exceeds the upper action value, to design the machine to reduce noise at source before relying on administrative or personal protective equipment controls. This means buyers should request the declared sound power level and sound pressure level at the operator position when evaluating food crusher specifications, particularly for bone crushers and heavy-duty grinders that operate at high motor powers and generate significant mechanical impact noise.
Vibration is a secondary but real concern for operators of manually fed crushing equipment. Where operators hold or guide material into the machine, hand-arm vibration transmitted through the feed mechanism must be assessed. Equipment designed with vibration-damped mounts and isolated drive systems reduces whole-body and hand-arm vibration exposure, which both protects workers and simplifies the employer’s compliance obligations under national transpositions of the Physical Agents Directive.
What are the key differences between standards for fresh and frozen material processing?
The key difference between standards for fresh and frozen material processing lies in the mechanical demands placed on the equipment and the corresponding safety requirements around structural integrity, guarding strength, and motor protection. Frozen material processing subjects crushers to significantly higher impact forces than fresh material, which means the risk assessment under EN ISO 12100 must account for greater energy release during crushing and the possibility of projectile fragments if guarding fails.
For fresh material, hygiene design standards dominate the compliance picture because the primary risks are microbiological contamination and physical hazard from moving parts. Drainage, surface finish, and cleaning accessibility are the critical design parameters. Temperature control requirements may also apply if the fresh material must be kept below specified temperatures during processing to comply with food safety regulations under Regulation (EC) No 852/2004 on food hygiene.
Frozen material processing introduces additional mechanical hazards. Guards and enclosures must be rated to contain fragments generated when hard frozen blocks or dense bone material is crushed at high force. Drive systems must be sized not only for continuous rated load but also for the peak torque spikes that occur when a particularly hard piece enters the crusher roll. Equipment designed for frozen block pre-crushing, such as heavy-duty bone crushers operating at 45 to 75 kW motor power, must demonstrate through the technical file that guards remain effective under these dynamic loading conditions. Facilities that process both fresh and frozen materials in the same equipment should ensure the risk assessment covers both operating modes explicitly.
How should food processing facilities verify crusher compliance before installation?
Food processing facilities should verify crusher compliance before installation by requesting and reviewing the EU Declaration of Conformity, the CE marking documentation, the technical file summary, and the harmonised standards applied, then cross-checking that the declared standards are current versions and that the risk assessment covers the specific materials and operating conditions intended for the facility.
A practical verification process before installation should cover the following areas. First, confirm the CE mark is present on the machine nameplate and that the Declaration of Conformity names the correct machine model and serial number. Next, verify that the harmonised standards listed in the Declaration are current and cover both machinery safety and food hygiene design. Buyers should also request the declared noise emission values and compare them against the facility’s noise risk assessment. Physical guarding, interlocks, and emergency stop functions should be inspected against the requirements described in the technical documentation. All food-contact materials must be documented as compliant with Regulation (EC) No 1935/2004, and the operating and maintenance manual must be available in the language of the country of use, as required by the Machinery Directive.
Beyond documentation, facilities should conduct a pre-installation site assessment to ensure the crusher is integrated into the production line in a way that does not introduce new hazards not covered by the manufacturer’s risk assessment. Modifications to guarding, feed arrangements, or discharge systems can void the CE marking if they materially alter the machine’s safety characteristics. Where bespoke integration is required, the facility may take on the role of manufacturer for the modified assembly and assume responsibility for a fresh conformity assessment. Working directly with the equipment supplier during the integration design phase is the most reliable way to avoid this situation and ensure that the installation remains fully compliant from day one.
