Medicine Food Grade Lab Scale Pulverizer Powder Making Machine Description:

The PNLP medicine and food grade lab scale pulverizer is configured for pharmaceutical, nutraceutical, and food laboratory environments where sample integrity, cross-contamination control, and batch documentation are quality system requirements — not just operational conveniences.

Cleaning validation between batches. The fully enclosed grinding chamber, disc assembly, and conveying path are designed for disassembly and cleaning between sample runs. For laboratories operating under GMP or HACCP quality systems, the PNLP’s compact internal geometry reduces the surface area requiring validated cleaning compared to larger production equipment — supporting faster changeover between formulations or product lines without compromising cleaning validation protocols.

Allergen and cross-contamination control. Food laboratories processing samples containing common allergens (nuts, gluten, dairy derivatives) alongside allergen-free formulations require dedicated cleaning procedures between runs. The PNLP’s accessible disc and chamber design supports the thorough wet or dry cleaning protocols typically required for allergen changeover, and its small batch size (10 lb hopper) limits the quantity of material in the system at any time — reducing both cleaning burden and product loss during changeover.

Batch parameter logging for documentation. The integrated controller records operating parameters (disc speed, temperature, run duration) for each batch, supporting the documentation requirements of pharmaceutical formulation development and food product quality control records.

Ambient and cryogenic modes. Both temperature modes are available on the same unit. Cryogenic (liquid nitrogen) mode is used for heat-sensitive active pharmaceutical ingredients (APIs), certain excipients, and food materials with low melting or softening points (fats, waxes, some encapsulated ingredients) that would degrade under ambient-mode friction heat.

 Medicine Food Grade Lab Scale Pulverizer Powder Making Machine Advantages：

Reduced cross-contamination risk between formulations. The enclosed grinding chamber and short conveying path minimise residual material between batches. For laboratories developing multiple formulations or processing both allergen-containing and allergen-free samples, this reduces the cleaning burden and contamination risk at each changeover.

Documentation-ready operation. Batch parameters (speed, temperature, duration) are logged by the integrated controller, supporting the record-keeping expectations of pharmaceutical R&D documentation and food product development quality records.

Suitable for heat-sensitive active ingredients and food materials. Cryogenic mode processes materials that would degrade, melt, or oxidise under ambient grinding conditions — relevant for certain APIs, encapsulated ingredients, fats, and waxes used in food and nutraceutical formulations.

Small batch sizes limit material loss. The 10 lb hopper capacity is sized for laboratory sample quantities — appropriate when working with expensive APIs, limited-availability ingredients, or small-batch food formulation trials where minimising waste is a cost consideration.

Compact, mobile unit for shared lab spaces. Casters allow repositioning between cleanroom-adjacent areas, formulation labs, or QC stations without dedicated installation — useful in facilities where the pulverizer is shared across multiple projects or departments.

Pulverizer for laboratories

WANROOETECH lab scale pulverizer offers the versatility and flexibility required for laboratory and pilot plant applications. It can be operated at both ambient and cryogenic temperatures. laboratory pulverizers can be used to grind polymers ranging from synthetic resins to rubber to adhesives, as well as pharmaceuticals, and even including food grades, into top-quality powder.

Application Areas

Pharmaceutical formulation development. Active pharmaceutical ingredients (APIs) and excipients are ground to target particle size for dissolution testing, bioavailability studies, and formulation screening. Cryogenic mode is used for heat-sensitive APIs where ambient grinding would risk thermal degradation or polymorphic transformation.

Food and nutraceutical R&D. Spices, dried ingredients, encapsulated additives, and nutraceutical raw materials are ground to target particle size for formulation development, dissolution profiling, and sensory testing. Allergen-containing and allergen-free samples are processed with full cleaning validation between runs.

QC particle size verification. Quality control laboratories use the PNLP to prepare ground samples for particle size analysis (laser diffraction, sieve analysis) as part of incoming material inspection or finished product release testing.

Cosmetic and personal care formulation. Powder cosmetic ingredients, mineral fillers, and active ingredients for skincare formulations are ground to target fineness for formulation trials — a related application area for laboratories with adjacent cosmetic R&D programmes.

Technical Features

• Fully enclosed grinding chamber, disassembly-friendly — designed for access during cleaning validation procedures between batches; supports allergen changeover and formulation-to-formulation cleaning protocols common in pharmaceutical and food laboratories.
• Ambient and cryogenic modes — cryogenic (liquid nitrogen) mode for heat-sensitive APIs, encapsulated ingredients, fats, and waxes that would degrade under ambient grinding friction heat.
• Integrated batch parameter logging — disc speed, temperature, and run duration recorded per batch; supports documentation requirements for pharmaceutical R&D and food quality records.
• 10 lb hopper — small batch sizes — appropriate for limited-availability APIs, expensive ingredients, and small-batch formulation trials where material loss must be minimised.
• 8-inch abrasive-resistant discs, 5 HP motor — sized for laboratory throughput up to 50 lbs/hr with precise particle separation via integrated 1-deck sifter.
• Multi-voltage configurations (460/60/3, 380/50/3, 415/50/3) — suitable for laboratories in North America, Europe, and other international regions.

Frequently Asked Questions

Can this pulverizer be cleaned and validated for use between different pharmaceutical or food formulations?

The PNLP’s grinding chamber, disc assembly, and conveying components are designed for disassembly, allowing access for wet or dry cleaning between batches. Cleaning validation itself is the responsibility of the laboratory’s quality system — WANROOETECH does not provide cleaning validation protocols, but can supply equipment drawings, material specifications, and surface finish documentation that laboratories typically require as input to their own validation procedures. The small internal volume of the PNLP (10 lb hopper, compact grinding chamber) reduces the surface area and residual material that needs to be addressed during cleaning compared to production-scale equipment.

What contact materials are used in the grinding chamber, and are they suitable for pharmaceutical or food applications?

Contact material specifications (grinding chamber, disc, and conveying surfaces) should be confirmed with WANROOETECH at the quotation stage based on your application — pharmaceutical, food, or general laboratory use may have different material and surface finish requirements. WANROOETECH can provide material certificates and surface finish documentation to support your facility’s incoming equipment qualification and contact-material compliance review (e.g. FDA food-contact substance regulations, EU Regulation 10/2011 for food-contact plastics, or pharmaceutical equipment material standards applicable in your region).

Why would a pharmaceutical or food lab need cryogenic grinding capability?

Many APIs, encapsulated ingredients, and food materials (fats, waxes, certain flavour encapsulations) have low melting or softening points, or are susceptible to thermal degradation, oxidation, or polymorphic transformation under the friction heat generated during ambient grinding. Cryogenic mode introduces liquid nitrogen into the grinding chamber, keeping material temperature low throughout processing and preventing these issues. For formulation development involving heat-sensitive actives or encapsulated ingredients, cryogenic capability is often a prerequisite for representative sample preparation — grinding at ambient temperature would alter the material’s properties before testing even begins.
