Description
Technical Field
[0001] The utility model relates to the technical field of sand flour production, in particular to a multi-stage vibration screening box for sand flour pretreatment. Background Art
[0002] Sand flour is a low-gluten flour with fine and soft powder and light texture. It is used to make cakes and pastries and other foods. It can make the food softer, easier to absorb liquid and better taste. Compared with ordinary gluten flour, the main difference between sand flour and ordinary gluten flour is that its protein content is lower, which makes it more suitable for making foods that require viscosity and low water content. In the production process of sand flour, in order to obtain sand flour with the same particle size, a screening box is used to screen it. At present, the multi-stage vibration screening box suitable for sand flour pretreatment on the market still has some disadvantages;
[0003] The existing multi-stage vibration screening box for sand flour pretreatment directly puts the sand flour into the vibration box, and the sand flour may be agglomerated, which may easily lead to blockage at the feeding port of the screening box. At the same time, directly using the sieve plate to screen the sand flour will cause problems such as uneven and incomplete screening. For example, the Chinese utility model patent with authorization announcement number CN220635218U discloses a vibration screening box for sand flour production, including: a box body for bearing and limiting, a storage bin fixedly connected to the box body, a first sieve plate and a second sieve plate fitted in the box body, and an adjustment rod arranged above the middle of the first sieve plate and the second sieve plate; it also includes: a symmetrical solenoid valve is fixedly installed on the inner side of the upper end of the box body, and a display, a buzzer and a controller are embedded on the inner side of the right rear upper end of the box body; the first sieve plate and the second sieve plate are respectively located on the inner side of the upper end and the inner side of the middle part of the box body. The vibrating screening box for sand flour production is convenient for controlling the amount of sand flour to be put in, and is convenient for sounding a reminder to add when the stock of sand flour is insufficient, and is convenient for multi-stage vibration screening of sand flour; it is convenient to avoid the blockage of the first screen plate and the second screen plate to improve the efficiency of vibration screening, and is convenient for cleaning and collecting the unscreened sand flour on the first screen plate and the second screen plate. However, this device has the problem of directly putting sand flour into the interior of the vibration box, and the sand flour may clump, which is easy to cause blockage at the feeding port of the screening box. At the same time, directly using the screen plate to screen the sand flour will cause problems such as uneven and incomplete screening. Therefore, we propose a multi-stage vibrating screening box for sand flour pretreatment to solve the above problems. Utility Model Content
