Chain Shell Washer
A chain shell washer is a specialized piece of equipment used in the seafood processing industry for the automated cleaning of shellfish, primarily clams, mussels, and oysters. It efficiently removes sand, mud, broken shell fragments, and other debris from harvested shellfish, preparing them for further processing or packaging.
Material:
- Frame: Typically constructed from stainless steel (grades 304 or 316) to resist corrosion from saltwater and ensure hygienic operation.
- Wash Tank: Also stainless steel, designed to hold a large volume of water.
- Chain: Heavy-duty, food-grade stainless steel chains are the core component, providing the scrubbing action.
- Agitators/Impellers: Often stainless steel, used to create water flow and keep debris suspended.
- Screens/Filters: Stainless steel mesh or perforated plates used to collect and remove debris.
- Pumps: Stainless steel or plastic pumps circulate water through the system.
Purpose:
The primary purpose of a chain shell washer is to improve the quality and safety of shellfish by removing contaminants. This reduces the risk of grit or foreign objects in the final product and extends shelf life. It also reduces labor costs associated with manual cleaning.
Function:
Chain shell washers operate on the principle of mechanical agitation and water flow. Shellfish are fed into a wash tank containing a continuous loop of heavy-duty chains. The chains, driven by a motor, move through the water, creating friction and impact that dislodges debris from the shells. The water flow carries the dislodged material towards a collection system, typically a series of screens or filters. The process often involves multiple stages of washing and screening.
Usage Scenarios:
- Large-Scale Seafood Processing Plants: Essential for handling high volumes of shellfish.
- Clam Farms: Used to clean clams before shipping or further processing.
- Mussel Farms: Similar to clam farms, for cleaning large quantities of mussels.
- Oyster Processing Facilities: For cleaning oysters prior to shucking or packaging.
- Shellfish Depuration Facilities: Can be used as a pre-wash before depuration (a process to remove bacteria).
Common Types:
- Drum Washers: Shellfish are tumbled within a rotating drum containing chains. These are often used for smaller volumes.
- Conveyor Washers: Shellfish are conveyed through a wash tank with chains providing the scrubbing action. Suitable for continuous processing.
- Multi-Stage Washers: Incorporate multiple wash tanks and screening stages for more thorough cleaning.
- Vibratory Washers: Utilize vibration to agitate the shellfish and dislodge debris.
- Jet Washers: Employ high-pressure water jets in addition to chain agitation for more intense cleaning. Often used for oysters.
Based on the provided information, “chain shell washer” can be interpreted as a washing machine used for cleaning chains, potentially within an industrial setting. Here are the relevant HS codes and explanations:
-
8451400000: Machinery for washing, cleaning, wringing, drying, ironing, pressing (including fusing presses), bleaching, dyeing, dressing, finishing, coating or impregnating textile yarns, fabrics or made up textile articles and machines for applying the paste to the base fabric or other support used in the manufacture of floor coverings such as linoleum; machines for reeling, unreeling, folding, cutting or pinking textile fabrics; parts thereof: Washing, bleaching or dyeing machines. This code covers machines specifically designed for washing, bleaching, or dyeing. While not explicitly mentioning chains, it could apply if the washer is used in a process related to textile treatment.
- Chapter 84: Machinery and mechanical appliances; parts thereof.
- Heading 8451: Machinery (other than machines of heading 8450) for washing, cleaning, wringing, drying, ironing, pressing (including fusing presses), bleaching, dyeing, dressing, finishing, coating or impregnating textile yarns, fabrics or made up textile articles and machines for applying the paste to the base fabric or other support used in the manufacture of floor coverings such as linoleum; machines for reeling, unreeling, folding, cutting or pinking textile fabrics; parts thereof.
- Subheading 8451400000: Washing, bleaching or dyeing machines.
-
8474100010: Machinery for sorting, screening, separating, washing, crushing, grinding, mixing or kneading earth, stone, ores or other mineral substances, in solid (including powder or paste) form; machinery for agglomerating, shaping or molding solid mineral fuels, ceramic paste, unhardened cements, plastering materials or other mineral products in powder or paste form; machines for forming foundry molds of sand; parts thereof: Sorting, screening, separating or washing machines Portable. This code applies to washing machines used for earth, stone, ores, or mineral substances. If the chain shell washer is used to clean chains containing these materials, this code may be applicable.
- Chapter 84: Machinery and mechanical appliances; parts thereof.
- Heading 8474: Machinery for sorting, screening, separating, washing, crushing, grinding, mixing or kneading earth, stone, ores or other mineral substances, in solid (including powder or paste) form; machinery for agglomerating, shaping or molding solid mineral fuels, ceramic paste, unhardened cements, plastering materials or other mineral products in powder or paste form; machines for forming foundry molds of sand; parts thereof.
- Subheading 8474100010: Sorting, screening, separating or washing machines Portable.
-
8451800000: Machinery (other than machines of heading 8450) for washing, cleaning, wringing, drying, ironing, pressing (including fusing presses), bleaching, dyeing, dressing, finishing, coating or impregnating textile yarns, fabrics or made up textile articles and machines for applying the paste to the base fabric or other support used in the manufacture of floor coverings such as linoleum; machines for reeling, unreeling, folding, cutting or pinking textile fabrics; parts thereof: Other machinery. This code covers other washing, cleaning, wringing, drying, ironing, pressing, bleaching, dyeing, dressing, finishing, coating or impregnating machinery not specifically classified elsewhere within heading 8451.
- Chapter 84: Machinery and mechanical appliances; parts thereof.
- Heading 8451: Machinery (other than machines of heading 8450) for washing, cleaning, wringing, drying, ironing, pressing (including fusing presses), bleaching, dyeing, dressing, finishing, coating or impregnating textile yarns, fabrics or made up textile articles and machines for applying the paste to the base fabric or other support used in the manufacture of floor coverings such as linoleum; machines for reeling, unreeling, folding, cutting or pinking textile fabrics; parts thereof.
- Subheading 8451800000: Other machinery.
It is important to note that the final HS code classification will depend on the specific design and function of the chain shell washer, as well as the materials being cleaned.
