Sanitary Sealed Cover Hopper
The Sealed Cover Hopper is a sanitary storage and dispensing vessel equipped with a fully sealed cover to protect contents from environmental contamination. The tight-sealing lid prevents dust, moisture and airborne particles from entering the hopper, making it ideal for handling hygroscopic materials and products that require strict contamination control. The sealed design also helps contain odors and prevents product spillage during processing.
This hopper is integrally spin-formed by spinning process with no welding marks on the body. It is constructed entirely from food-grade stainless steel with all welds ground and polished smooth to eliminate crevices where bacteria could accumulate. It is designed for quick disassembly without tools to facilitate thorough cleaning and inspection.
