Import 304# Stainless Steel Blast Freezer — Buy in wholesale FOB from Supplier in China

This 304# stainless steel blast freezer is an industrial rapid-freezing unit built for food processing operations where speed and temperature control determine product quality. The unit reaches temperatures as low as -40°C, which arrests cellular activity quickly enough to minimise ice crystal formation and preserve texture in delicate proteins. The entire cabinet and interior contact surfaces are fabricated from 304 austenitic stainless steel, a grade containing 18% chromium and 8% nickel that resists chloride corrosion and permits aggressive cleaning protocols. Hk Supermarket Equipment Co., Ltd. offers this unit in multiple capacity configurations, though exact chamber dimensions and throughput ratings in kg per hour are not stated in the listing and should be confirmed directly with the supplier.

In commercial blast freezing, the 304 stainless steel construction is significant because it meets NSF and EHEDG hygiene expectations without the delamination risks of coated steels. The material is non-magnetic, weldable for custom fittings, and maintains its ductility at cryogenic temperatures. Typical wall thickness for such cabinets ranges from 1.2mm to 2.0mm, with injected polyurethane foam insulation between inner and outer skins to achieve thermal conductivity values around 0.022 W/mK. The refrigeration system will almost certainly use a multi-stage compressor arrangement with refrigerants such as R404A, R448A, or R449A, though the exact charge and compressor brand are supplier-specific details to verify. Fans are typically axial or centrifugal types rated for high static pressure to force air past evaporator coils at velocities of 3-5 m/s.

Buyers for this equipment include meat and poultry processors, seafood cold-store operators, ready-meal manufacturers, and large-scale bakery facilities. The blast freezer sits downstream of cooking or upstream of long-term storage, acting as a bottleneck prevention point. When sourcing from Hk Supermarket Equipment Co., Ltd. in China, you should confirm the electrical specification (voltage, phase, and frequency), the refrigerant type in light of regional environmental regulations, and whether the control system offers programmable freezing curves with core temperature probes. Shipping terms such as FOB or CIF are noted as flexible, but exact Incoterms, lead times, and installation support must be negotiated directly with the supplier.

Hk Supermarket Equipment Co., Ltd. is headquartered on Kowloon Road in Hong Kong, with operations extending into mainland China as indicated by its supplier address in the 510000 postal zone. The company carries an imported supplier tier designation and a harbor trust tier, which indicates a baseline level of platform verification though not the highest available. The response rate is recorded at 0.00% with zero average response hours, meaning buyer outreach through standard channels may not receive prompt replies and direct follow-up by alternative methods is advisable. The listing presents the company as a source of commercial refrigeration and food-service equipment, but it does not state when the business was established, how many staff it employs, or what production facilities it operates.

The source description contains no verified certifications such as ISO 9001, CE marking for the blast freezer, or NSF listings, and these should not be assumed. No client references, annual revenue figures, or factory audit results are provided. The supplier's product range appears centred on stainless steel refrigeration for food retail and processing environments, with blast freezers representing one category within a broader equipment catalogue. Buyers should treat the company as a trading or manufacturing intermediary subject to standard due diligence, requesting business registration documents, product test reports, and references from previous export shipments before committing to an order.
