Description

TECHNICAL FIELD

[0001] The application relates to the technical field of food processing, in particular to an automatic food processing raw material pretreatment device. BACKGROUND

[0002] Food processing pretreatment is an important link in food production, aiming to improve food quality, safety and processing efficiency. Pretreatment process includes a series of operations such as selection, cleaning, grading, peeling, cutting, blanching and cooling of raw materials. Through these steps, impurities and undesirable parts in the raw materials can be removed, and the size and shape of the food can be adjusted to make it more suitable for subsequent processing and cooking. At the same time, pretreatment can also destroy the enzyme activity and microorganisms in the raw materials, prolonging the shelf life of the food. Therefore, scientific and reasonable food processing pretreatment is of great significance to ensure the quality and safety of food, and is also the basis for realizing the industrialized production of food.

[0003] The patent with Chinese publication number CN213504581 U discloses a food processing pretreatment equipment, the structure of which comprises an equipment box, an inlet, a control box, an oil inlet, an auxiliary roller, a first track, a second track, and a collection box. The equipment box is welded to the control box, the inlet is fixed to the upper end of the equipment box, the oil inlet is movably connected to the auxiliary roller, the first track is fixed to the upper end of the second track, and the collection box is fixed to the lower end of the second track. Inside the equipment box, there are a support, a roller, a cleaning device, and a guide rod. The support is nested with the roller, the cleaning device is movably connected to the guide rod, and the rubber scraper and the sponge roller on the cleaning device clean the track at any time. The garbage after cleaning falls into the collection box for collection, and the track is further wiped by the sponge roller to ensure that it is clean and tidy. This pretreatment equipment avoids the problem that residual food on the track is easy to breed bacteria, or that residual food sticks to the food, causing the food to be unqualified after being detected after leaving the factory.

[0004] The cleaning device in the above patent file cleans the track by setting rubber scrapers and sponge rollers. The rubber scrapers in the cleaning device need to run through the track to remove the residues on the track during use. Although the above cleaning process can achieve the purpose of cleaning, the rubber scrapers cannot rotate due to the use of a single set of rubber scrapers, resulting in low cleaning efficiency of the rubber scrapers. Therefore, an automatic food processing raw material pretreatment device is proposed. CONTENT OF THE UTILITY MODEL

A third servo motor drives a drive gear to rotate, which in turn drives a driven gear, which in turn drives a splined shaft to rotate. This rotation of the splined shaft simultaneously rotates a support frame, which in turn drives a scraper to rotate. This allows the scraper to rapidly and repeatedly clean the surface of the conveying mechanism while it rotates, solving the problem of insufficient cleaning by the scraper and effectively preventing the risk of bacterial growth from residues on the conveying mechanism, thus avoiding food contamination.
