Sanitary Conveyors

​

Sanitary Goods Conveyors are utilized primarily with direct contact food & dairy products and pharmaceuticals with high pressure and caustic sanitation requirements.  These products are designed to not harbor debris, are easy to clean, and drain after sanitation cycles.  

Sanitary good conveyors are highly customizable to be able to work in the toughest sanitation requirements.  Deciding where to stop and start the sanitary goods conveyors can  in project cost.

Please contact CLE as early as possible in the design phase to assist with requirements and specifications. Our engineering team can work with you to make sure requirements are met without going overboard on options.  

Frame construction for sanitary goods conveyors is critically important.  CLE uses 11 gauge 304 stainless steel shells for the outer frame members with #4 grain polish as standard.  316L stainless steel can be provided upon request. Larger, heavier load conveyors may require 10 gage or 7 gage side frames.

CLE frame spreaders are solid design (round bar or vertically standing flat bar) so that there are no hollow areas for growth to occur.  Spreaders are 100% welded to the frames with ground and polished welds. Bearings, drives, guide rail brackets and other accessories are attached via external frame mounted stand- offs which are 100% welded to frame.

Clean out/inspection holes can be provided for high pressure nozzle access when requested.  Although not required by ANSI guidelines, please consult with your corporate safety standards for clean out guard requirements. 

Vertical flat bar wear strip backings with snap on Ultra High Molecular Weight Polyethylene (UHME-PE) wear strip cover are standard for sanitary goods conveyors and offer good chemical resistance to common caustics and cleaning solutions.  We will review your material data safety sheets (MSDS), cleaning schedule, and procedure documentation for your application. For strict environments, CLE can provide stainless steel wear strips or toolless removeable UHMW-PE wear strips (belt lifters and quick access idler shaft recommended) where required.

CLE recommends formed angle supports for the most sanitary conveyors to remove areas of potential bacterial growth.  Supports are laser cut with smooth feature profiles and are length specific to minimize the number of unused holes. Support spreaders are set at a 45 degree angle for draining.  CLE provides supports with adjustable flat plate supports or various articulating levelers. Contact CLE for specific requests.

There are many options for drive choices for sanitary goods conveyors.  For most applications, we recommend using a shaft-mounted, high-efficiency helical-bevel gear-motor with a stainless steel quick release device. These units can be supplied with premium efficient invert-duty motors and NSD sealed surface conversion system for wash down use.  CLE also provides stainless steel worm gears with stainless steel motors when requested, but high external motor and reducer temperatures must be considered.  For the utmost sanitary design, CLE offers stainless steel motorized pulleys.  Please contact CLE for specific drive options.

Guide rail requirements are largely dependent upon the product being conveyed and line speed. CLE offers a variety of sanitary design guide rail systems with fixed and adjustable options. We can also assist with custom toolless repeatable and pneumatic adjusting rails to ensure quick change overs for maximum line efficiency. CLE can provide extended side frame design for integrated guide rail.

Special requirements for Electrical and Controls System design in sanitary and wash down environments are handled by CLE electrical engineers who have vast experience in working with tough wash down applications found in food, beverage, and pharmaceutical applications.  Please contact CLE as early as possible to get expert guidance on component selection and electrical system/installation design for cost effective solution in wash down and sanitary environments.

Typical made to order design and options are:

• Sanitary conveyor design for ease of cleaning

• 3A and USDA  compliant designs and materials where required

• Solid frame members

• 304 SS frame with continuous TIG weld  (316L available)

• H1 FDA compliant lubricants

• Welded stand offs for bearings, guiderail brackets, supports, and other accessories to keep hardware out of food zone

• Optional nosebar drive and tail ends for tight product transfers

• CIP spray bars are optional

• Clean out/inspection holes on side of conveyors frames

• 1.5” square SS shafts to reduce harborage points

• Formed SS angle supports with no horizontal members
