What Is the Heating Mode of Tunnel Oven?

Views:1     Author:Site Editor     Publish Time: 2019-04-22      Origin:Site

We can always see tunnel oven in cake production line and biscuit production line in bakery and factory. Hot air circulation is a common heating method of tunnel oven at present. It uses the principle of convection conduction to heat the oven to achieve the drying and curing of the work-piece.


Tunnel Oven


What is a convection?

Simply put, convection oven equipment like spiral cooling tower has a fan and an exhaust system that a regular oven does not. Fans and exhaust devices help to blow hot air around the food and then deprive it. As a result, Hot air surrounds the food and top service it cook more evenly and quickly.


A good way to describe this comes from fine cooking: "to help understand this, consider wind chill: When cold air blows over you on a windswept winter day, you feel colder faster than on a windless day with the same temperature. "the same goes for heat and convection cooking!


The heat source can be chosen according to the user's specific situation: electricity, steam, gas or fuel, etc. The heat source box can be placed on the top, bottom and side according to the conditions of the oven. The production of heat source of the circulation fan such as special high temperature fan, it has a long life, low energy consumption, low noise, small size and other advantages.

The production of heat source of the circulation fan such as special high temperature fan, it has a long life, low energy consumption, low noise, small size and other advantages. -- the working principle of infrared tunnel oven equipment (drying line) is generally to use far infrared to heat the furnace, and then the inner is made of ceramics and stainless steel, so that the infrared ray can shine into every corner of the furnace, and then uniform heating, the energy will be transmitted to the object.


The tunnel oven is designed and manufactured by foreign advanced technology, with advanced structure, simple disassembly and assembly, and beautiful appearance. High technology heat preservation material has good heat insulation performance and strong heat preservation, the heating technology adopts far infrared heating technology. The heating element layout is reasonable, and the energy consumption is low. Internal hot air circulation, so that the upper and lower temperatures in the furnace more uniform, no loopholes, to ensure the quality of oven products. Tunnel oven is one of the important equipment in coating production line. Its temperature uniformity is an important index to guarantee coating quality. Oven heating methods are: radiation, hot air circulation and radiation + hot air circulation, etc., according to the production program can be divided into single room and through type, etc.
