Description

Automatic raw material cleaning equipment

Technical Field

The invention relates to general cleaning equipment, in particular to automatic cleaning equipment suitable for cubilose raw materials and also suitable for cleaning agricultural and sideline products and traditional Chinese medicinal materials which need to be repeatedly washed.

Background

Bird's nest (also called bird's cup) belongs to one of agricultural and sideline products. The bird's nest is a nest formed by mixing and bonding saliva and down feather secreted by several swiftlets of the family Ranidae. The cubilose contains abundant organic acid, free amino acid and characteristic substance-sialic acid. The bird's nest is considered by traditional Chinese pharmacology to have the effects of reducing phlegm, moistening throat, relieving stomach illness, assisting kidney functions, relieving asthma and the like. In the 20 th century, with the development of pharmacological research techniques, researchers began to utilize modern pharmacological research means to research bioactive components in bird's nest and efficacy mechanisms thereof. The research of the scholars at home and abroad at present shows that the cubilose has the following biological activities of potential promotion of cell proliferation and epidermal growth factor activity, improvement of gastrointestinal function, anti-influenza virus and blood coagulation inhibition activity, lectin binding property, improvement of bone density and epidermal thickness, antioxidation, immunity enhancement, hormone treatment, tracheitis, anaphylactic reaction and other activities.

Swiftlet is a special swallow, can only survive in tropical rain forest and island environment, mainly distributed in southeast Asia island, and also in China, such as Nansha Islands, yunnan southern, etc., but very few. Indonesia islands are much more numerous than other countries in south-east asia, so indonesia has the largest bird's nest yield. Indonesia's bird's nest production accounts for 80% of the world, 10% from Malaysia and 10% in other regions. Since bird's nest is a natural product in nature, bird's nest raw material (bird's nest) has bird's hair, droppings, weeds, egg shells, hair, fibers, etc. based on the natural conditions of its formation. Therefore, in the process of preparing the edible bird's nest into the filling product which can be sold on the market from the raw materials, firstly, impurities are completely and thoroughly removed, so that the quality of the edible bird's nest product processed at the later stage is ensured.

At present, the conventional cleaning operation of the bird's nest comprises cleaning after soaking, the cleaning process is that the bird's nest raw material which is placed in a screen and soaked is manually placed under a water tap and is washed by a large amount of clear water, and in the washing process, the bird's nest raw material is manually and continuously stirred so as to achieve the effect of thorough cleaning. Although a large amount of clean water and manpower are consumed in the cleaning process, only dust and fine impurities which can be dissolved in water or pass through a screen can be cleaned, and because other impurities such as fibers, hairs and the like which are fine and long and impurities with large particles which cannot pass through a screen hole exist in the bird nest, the impurities cannot be cleaned by washing in the screen hole and need to be manually picked one by one under specific environments such as a blackboard in the subsequent process, a large amount of manpower is consumed in the impurity removal and cleaning link of the bird nest raw material, and the bird nest product has high labor cost.

In the screen washing process, if a screen with a small mesh number (namely a screen with a large mesh) is adopted, more swallow shreds can be lost although the screen can be cleaned more cleanly, and the raw material of the swallow nest is also a relatively expensive natural product, so that the loss is large, the cost is not controlled easily, and serious waste is caused.

In the prior art, as the novel cleaning equipment for cubilose production disclosed in the Chinese utility model patent with the publication number of CN208082977U, the automation degree of the cleaning equipment is not improved, the continuous cleaning operation cannot be realized, and the cleaning effect is not obviously improved compared with the manual cleaning; an automatic bubble belt cleaning device that discloses in the chinese utility model patent of grant publication No. CN214718895U, if the device is used for the preliminary washing of swallow cup, can replace artifical manual stirring swallow silk to a certain extent, but the impurity that can clear away is limited to also exist not enoughly in the degree of automation.
