Conveyor Oven

Conveyor oven used in vegetable dehydration have multiple belts in line, and the feed is transferred from one belt to another.

Multiple heat zones

Extended loading and unloading zones

Special belt construction or attachments

Cooling zone to reduce part temperature

Our experienced engineers will work closely with you to develop a conveyor oven to meet your particular requirements. Every unit is completely assembled and tested. You are invited to witness test and run sample parts at our factory prior to shipment.

• Aluminized or stainless steel interior depending on maximum temperature rating.
• 16 gauge aluminized steel exterior with enamel finish
• Welded structural steel, channel base provides a rigid assembly easily moved at any time.
• Heavy duty, all welded, structural steel slide bed is supported by cross angles welded to vertical structural members to transfer load to base
• Belt slide bed herringbone construction provides for even belt wear.
• Side hinged doors provided along oven length for access to work space and heat chamber.
• Heavy duty variable speed belt drive with torque limiting device
• Belt tracked and guided as necessary with rollers to prevent wandering and potential belt damage
• Adjustable dampers at each end of heat zone can be positioned near load to minimize heat loss from end of oven.
• Adjustable patented opposed louvers on full coverage supply and return ductwork.
• Duct work removable for cleaning
• Brushed stainless steel control panel face

To determine if a belt conveyor oven is practical for your application, estimate the heated tunnel length. Belt conveyor equipment is sized to the application based on part dimensions, production rate and dwell time.
Belt width is selected to accommodate the desired loading pattern, such as in line, side by side or four abreast. The loading density, parts per lineal foot, and production rate determine the design belt speed. The design heat zone length is the product of belt speed and dwell time.

It is important to understand the relationship between belt width, production rate and heat zone length. Doubling the belt width will double the production rate, or allow the heat zone to be half as long.

To estimate the length of belt conveyor equipment required for your application, insert your process information in the relationships below. To the heat zone length calculated, the length of load zone and unload zone must be added. Approximately 2 additional feet of length will be required for belt guarding and drive.

Equipment width will be approximately 3 feet wider than belt width to accommodate insulation, duct work and control enclosure.

(Production rate of …………parts per hour)                   = (Belt speed of ………. feet per hour)
(Loading density of ……….parts per lineal foot)
(Belt speed of ….. feet per hour) X (Dwell time of ….. hour) = (Heat zone length of ………. feet)
