Technical requirements and instructions for hot air circulation oven

(contract attachment)

  • use:

Dry dried tofu

  • Features:

The design, production, technology and process of Suzhong Pharmaceutical Machinery Co., Ltd. of Taixing City, Jiangsu Province reached the level of domestic ling.

The product adopts low noise and high temperature resistant axial flow fan, equipped with intelligent temperature controller automatic temperature control system device, and the temperature rise and constant temperature process are stable. The temperature sensor is used to control the temperature control accurately, and the moisture discharge is proportional to the timed moisture discharge. For the fully enclosed structure, the matching baking tray is a wire mesh baking tray stainless steel square tube rack.

  • Working principle and effect:

Under the action of forced ventilation, the circulating fan will adjust the air conditioning plate inside the box. After the hot air is evenly distributed, the material will be heated and then heated by circulation. The humid air is automatically forced out of the box by the moisture exhaust port, so that it can be reciprocated to dry. The effect is that the material to be dried is evenly heated, and the tofu in the baking tray of each layer is in the same oven, and the appearance color is uniform after drying.

  8. Baking tray: all stainless steel SUS304, baking tray for wire mesh, stainless steel square tube basket, specifications: 460 × 640mm, stainless steel wire diameter of 1.2mm.
  9. Axial flow fan: air volume 3500m3/h/set, fan power 450W/each, voltage 380V for cast aluminum fan, decoration on the side of the box, a total of 12 units.
  10. There are 2 drying machines for each oven, 12 ovens for 6 ovens, 48 ​​for each baking tray and 288 ovens for 6 ovens. The main material of the drying machine is stainless steel square tube and stainless steel plate. The stainless steel plate is bent into a track. The material is SUS304 with a thickness of 1.5mm, the stainless steel square tube is 38 × 25mm, and the tube thickness is 1.2mm. The drying wheel is a high temperature resistant wheel. The shape of the drying car is 695 x 920 x 1440 mm.
  11. Supporting the feeding rack 2, the material is SUS304 stainless steel plate, the plate thickness is 2.0mm.
  12. The square corners of the box are all right angles, and the outer surface of the box has no unevenness, which is smooth and beautiful.
  13. The joints of the plate in the box are formed by arc welding spot welding and fasteners.
  14. The door is opened on the front side (narrow side), the door structure is a compact structure, and the door seal is a silicone rubber seal.

Good insulation performance.

  1. The oven has two wet ports, and the top wet port device has one forced exhaust fan.
  2. The track groove is a closed track groove, which is convenient for the insulation inside the box and the bacteria to enter the box.
  3. The oven control device is mounted on the side of the cabinet for easy access.
  4. The shape of the oven is: 2210 × 1400 × 2000mm, the inner size is: 2000 × 800 × 1470mm, drying car

The upper and lower layers of each layer are 10mm apart, and each layer has 2 baking trays. The size of the baking tray is 460×640mm. The outer sheet is SUS304 stainless steel sheet, the thickness is 1.0mm, and the inner plate is 1.0mm. It is a laminated matt board.

  1. Studio size: the width of the facade is 800 × depth 2000 × height 1470mm, and the inner sheet is SUS304 stainless steel.
