What are Conveyor Washers?

Conveyor washers are inline washing machines that utilize conveyor belts to move or pass parts through a tunnel for cleaning stages. These machines are also often referred to as inline washers, pass-through washers, tunnel washers, and belt washers. Conveyor machines wash parts directly in a production line and are often used for high-volume cleaning applications. 

Conveyor Washer Design

BE builds standard conveyor washers with wash, rinse, and dry modules/cycles and uses environmentally safe water-based solutions for cleaning applications. Additional cycles for rinsing, rust-inhibiting, sealing, phosphate coating, and sanitizing can also be added. Better Engineering constructs conveyor washers with a modular design. This allows customers to easily add modules/cycles in the field with only bolts. These systems are versatile and can integrate into a handling line or function as stand-alone systems. 

These washers can range from single-stage, wash-only systems to large, multi-stage systems, and the flow can be continuous, indexing, or intermittent to accommodate different processes. Splash curtains or with zone dividers separate modules to help prevent cross-contamination from one zone to another. Belt widths also vary in size from small, 6-inch wide belts to belts as wide as 150-inches. Other variables involved in building a conveyor washer include tunnel height, weight capacity, tank size, load and unload requirements, and heating methods (electric, gas, or steam). High-quality systems have stainless steel construction, so they are resistant to corrosion. 

Types of Belts

Conveyor washers use various belt options such as continuous flat-wire, wire mesh, interlocking plastic, roller, and chain belts. These fixtures anchor parts in place. Guide rails, either fixed or adjustable, secure components to the belt. Additionally, BE builds systems that are linear or designed with U-bend, inclined and also return conveyor belts. streamline workflow and create an efficient and cost-effective solution to handling parts.


Industries served by conveyor washers include general manufacturing, automotive, aerospace, machining, surface preparation, food, pharma, medical, cosmetic, and more. Conveyor washers suit a wide variety of cleaning applications such as: 

  • removing chips, oils, grease, coolants, and buffing compound from machine parts, castings, housings, and stampings
  • cleaning before powder coating, deburring, brazing, blasting, welding, or other surface cleanliness critical post-process
  • remove fats, sugars, oils, allergens, and other organic material from food manufacturing processes
  • sanitize components used in food, pharma, medical, and cosmetic processes


There is no single solution to accommodate every different type of part in such a variety of industries. Each application has different machine needs based on the level of cleaning required. Better Engineering’s machines can comply with several manufacturing standards as FSMAHACCP, and GMP.

Better Engineering’s conveyor washers are highly customizable to meet each customer’s individual needs. Additionally, machines may include robotic integration, high-pressure pumps, high-speed belts, vacuum drying, and several other features.
