Food Pre-processing Equipment Manufacturer for IQF Freezing Lines
KLONG provides food pre-processing equipment for factories that need reliable preparation before IQF freezing, drying, packing, or further production. Before raw materials enter the freezer, they usually need cleaning, peeling, cooking, blanching, cooling, dewatering, air drying, sorting, lifting, distributing, and manual inspection. A well-designed pre-processing section helps improve product hygiene, freezing quality, production efficiency, and final product consistency.
Our equipment range includes bubble washing machines, mesh belt cooking machines, spiral cooking machines, normal-temperature water coolers, ice water pre-coolers, vibrating dewatering machines, vibrating distributors, manual sorting conveyors, elevators, belt-type air drying machines, winnowing machines, potato washing and peeling machines, and other auxiliary equipment. KLONG can help customers build a complete pre-treatment solution according to product type, processing capacity, factory layout, and downstream freezing requirements.
Build a Complete Pre-processing Line Before Freezing
Food pre-processing is the foundation of a stable freezing line. Different raw materials need different treatment before they enter the IQF freezer. Vegetables may require washing, blanching, cooling, dewatering, and distributing. Seafood may require washing, sorting, grading, draining, and conveying. Potato products may require washing, peeling, cutting, blanching, cooling, and surface water removal.
KLONG can combine single machines into a connected production line. For example, a typical vegetable freezing line may include a bubble washing machine, blanching machine, cooling machine, vibrating dewatering machine, air drying machine, elevator, vibrating distributor, and IQF freezer. By matching each section correctly, the whole line can run more smoothly with less manual handling and more stable product quality.
