Description

Technical Field

[0001] This utility model relates to the field of food processing technology, specifically to a tunnel drying oven for meal replacement biscuits. Background Technology

[0002] Tunnel drying ovens, also known as tunnel dryers, operate by placing the material to be dried on drying trays, which are then placed on drying carts. The drying carts enter the drying chamber sequentially from the inlet. Simultaneously, hot air is supplied from the material outlet of the drying chamber by the air supply system, flowing in the opposite direction to the drying carts to ensure thorough contact with the material. The drying chamber has automatic temperature control, and moisture is automatically discharged by an exhaust fan. To meet the growing demand, tunnel dryers have become widely available on the market.

[0003] Chinese Patent No. CN221505555U discloses an automatic drying tunnel oven, relating to the field of tunnel oven technology. The oven includes a tunnel oven with a support frame on its inner side and a drive belt on the outer side. A sliding frame is also located on the inner side of the tunnel oven, and a spray frame is slidably connected to the inner side of the sliding frame. A threaded rod is threadedly connected to the top of the spray frame. This invention utilizes the threaded rod in conjunction with a translation motor to provide effective transmission and drive, facilitating the back-and-forth movement of the spray frame within the tunnel oven. Simultaneously, a delivery pump, in conjunction with a right-angle pipe, draws cleaning and disinfecting liquid from the water tank, which is then transported through a hose to a connecting pipe, and then further to the interior of the spray frame. The cleaning and disinfecting liquid is sprayed out through evenly distributed nozzles at the bottom, disinfecting and cleaning the interior of the tunnel oven. This improves hygiene and safety, reduces bacterial growth, and enhances food safety.

[0004] However, the above technical solution has the following shortcomings: the interior of the tunnel oven can only be disinfected and cleaned when it is not in the drying state. During the drying process, food crumbs are constantly generated, and the crumbs on the conveyor belt cannot be cleaned in a timely and effective manner, which can easily affect the quality and appearance of the finished biscuits.
