一. What is a layer oven?
The layer oven is one of the most common and commonly used industrial ovens, with multiple layers of construction; each layer is an independent oven commonly used in the baking industry, which can quickly bake such food as bread, cake, and dessert. Compared with the tunnel furnace, the layer oven occupies less space than the large assembly line type baking equipment, and the multi-layer oven makes the space utilization rate larger, which is widely used in baking shops, food processing plants, and other scenes.
二. Layer Oven Structure
With a brief introduction to the layer oven, the following provides you with an insight into the structure of the layer oven to become more familiar with the machine:
1. Complete machine casing: the casing is generally square, made of stainless steel, resistant to high temperature and oil stain. The bottom of the housing is usually provided with universal wheels or feet for ease of movement; Partitions are provided in the enclosure to separate multiple layers of furnaces.
2.Furnace: Each layer is an independent furnace, and two adjacent furnaces and the insulation interlayer between the furnace and the shell have good insulation effect; The furnace is covered with stainless steel liner, which is rustless and easy to clean; The bottom of the furnace is paved with refractory stone plate, with good heat storage and heat conduction effects; Each furnace is equipped with a furnace door, which is usually made of high-temperature tempered glass, so as to observe the baking condition in the furnace; Sealants are set around the furnace door to prevent heat loss from the furnace door gap.
3. Heating system: each layer is equipped with a set of independent temperature control systems, including the upper heating tube and the lower heating tube. The feeding and primer temperatures of each layer are separately controlled by the heating tube. A temperature measuring probe is set at the upper and lower parts, which can collect the temperature in real time.
4. Control panel: generally one for each layer, with primer and primer temperature adjustment knobs, baking timer, and damper adjustment buttons.
三. Working Process of Grate Oven
With an understanding of the machine structure, the following is an introduction to the working process of the grate oven to help you become familiar with the role and importance of each structure:
1. Startup preheating: turn on the power first, and then set the baking temperature of each layer separately on each control panel (set the baking temperature and primer temperature separately), baking time and air door size, and start the heating after setting.
temperature. 2. Oven baking: open the oven door, put the baking tray containing food into the furnace, and then close the oven door. During baking, the temperature-measuring probe will monitor the temperature in the furnace in real time, and automatically maintain constant temperature after reaching the set temperature.
3. Shutdown and discharging: After baking, the heating pipe will automatically stop heating, and the buzzer will sound as a reminder. At this time, open the oven door, carefully pull out the baking plate, and remove the finished product.
4. Shutdown and cleaning: After all baking, turn off the heating of each layer, turn off the main power supply after the furnace cools down, and then clean the inner wall of the furnace and the baking plate.
四. Layer oven Vendor Selection?
With an understanding of the machine structure and working process, let’s talk about how to select an industrial oven manufacturer to purchase a quality machine. You should pay attention to the following points when selecting a supplier:
1. Give priority to the regular source manufacturers specialized in the industrial oven field for many years: they have the ability of R&D, production, sales, and service integration; complete business licenses; export qualifications and customs declaration formalities; and own plants and can take you to the site inspection or send workshop live video.
2. Machine quality: 304 food-grade stainless steel must be used for the hearth liner and the food-contact part of the baking plate. The thickness of the insulation cotton shall not be less than 80mm. The tempering and primer of each layer must be controlled independently, and the temperature control accuracy shall be within ± 2 – 3 °C.
3. Capacity matching: select the matching machine specifications according to the required capacity, such as two layers, three layers, four layers, and six layers.
4. Price: Comprehensively compare the quality and configuration of the machine, and do not just choose cheap ones. After all, one price for one product.
5. After-sales service for industrial ovens: the complete machine shall be guaranteed for at least one year, and the maintenance speed, replacement and supply of accessories, and express service shall also be observed.
五. Summary
Having reviewed the above, you are confident that you have learned how to purchase a great oven and hope it will help you select the appropriate industrial oven manufacturer to purchase the desired equipment.

六. FAQ
A: Generally, small shops can choose two-story and four-plate shops; medium-sized baking shops can choose four-floor shops; and large hotels and food processing plants can choose six-floor shops.
A: The baking time of each furnace is about 12-20 minutes. Taking the example of two layers and four plates, about 120-160 plates can be baked in 8 hours.
A: The furnace and baking plate shall be made of 304 food-grade stainless steel, and the shell shall not contact food materials. Generally, 201 stainless steel can be used to reduce cost.
A: Usually, they are made of fire-resistant stone plates, which can make the bottom of bread and French bars crisp; if only cake and biscuits are made instead of bread, steel plates can be used to reduce the purchase cost.
