Description

Technical Field

[0001] The invention relates to the technical field of bean filling processing, and more specifically, to a sand washing device for making bean filling. Background Art

[0002] Bean fillings refer to fillings made from beans as the main raw material after a series of processing (such as soaking, cooking, crushing, frying, etc.). They are used to make various snacks, pastries, moon cakes and other foods. The most representative bean filling is red bean paste. In the process of making red bean paste, it generally goes through three steps: boiling beans, grinding, and frying. The bean skin is relatively rough. If the bean skin is not removed during the process of making red bean paste, it will affect the taste of the red bean paste. In order to solve this problem, a sand washing equipment for bean filling processing has been designed. The bean skin and sand can be separated during the process of making bean filling to improve the taste of the finished red bean paste. This step The first step is usually called sand washing. Generally, the boiled beans are poured into the pulper of the sand washing equipment. The skin and pulp are beaten together through rotation and friction, and then flow into the mesh screen. During the flushing and rotation process, the mesh screen intercepts the skin to one outlet, while the sand flows into the sand washing tank through the mesh along the water. The mixture in the sand washing tank is stirred by the air pump and after a period of sedimentation, the water containing bean gum and starch in the upper layer will be released, and then clean water is added for multiple stirring and sedimentation, so as to gradually remove the bean gum and starch and improve the taste of the finished bean paste. However, adding water to wash the sand multiple times will waste a lot of water resources. At the same time, it takes a long time to separate the bean paste and water by static sedimentation, which reduces the efficiency of sand washing.

[0003] The utility model patent with application number 202222728742.9 discloses a bean peeling and sand washing integrated machine. Through the setting of the feed port, peeling box, servo motor, sand roller, screw propeller, transmission mechanism and bean pulping mechanism, the dry beans are poured into the peeling box from the feed port. The servo motor drives the sand roller and the screw propeller to rotate. The screw propeller drives the dry beans to spirally propel to the right on the surface of the sand roller. The surface of the sand roller and the bean skin rub against each other to make the skin fall off. Driven by the transmission mechanism, the dry beans are poured into the bean pulping mechanism for bean pulping to obtain The bean paste slurry mixed with bean skin can completely remove the bean skin when the beans are dried, and there is no need to filter the bean skin impurities layer by layer, so as to ensure the delicate taste of the bean paste. Through the arrangement of a slurry pump, a slurry pipe, a slurry pipe, a bean paste placement box and a filter cloth, the slurry pump draws out the bean paste slurry through the slurry pipe, and the sucked up bean paste slurry is transported to the bean paste placement box through the slurry pipe, and the water is filtered out through the filter cloth, and the bean paste is left on the filter cloth, so that the bean paste and water are filtered and separated, and the sand washing is completed. The operation is convenient, time-saving and labor-saving.

[0004] However, it is generally necessary to perform multiple operations of adding water, standing and settling, and draining water in order to remove part of the bean glue and starch in the bean paste slurry to improve the taste of the finished bean paste. According to the above technical scheme, if the sand washing operation of adding water, standing and settling, draining and filtering is performed multiple times, not only the water used for sand washing cannot be recycled, resulting in a waste of water resources, but also a lot of time is required for standing and settling to separate the bean paste and water, resulting in low sand washing efficiency.

The sand washing unit 03 includes a sand washing box 7, a vacuum pump 8, a water tank 9, a first water pump 10, a transfer box 11 and a filter cloth 12. A filter hole 13 corresponding to the screen barrel 1 is opened at the bottom of the sand washing box 7. The filter cloth 12 is laid on the bottom of the sand washing box 7 and covers the filter hole 13. The filter cloth 12 is a filter cloth 12 specially used for filtering bean paste on the market. A main water pipe 14 corresponding to the filter hole 13 is installed at the bottom of the outer wall of the sand washing box 7. The main water pipe 14 is funnel-shaped and can be disassembled and connected to the transfer box 11. The transfer box 11 is placed below the sand washing box 7, and the main water pipe 14 is connected to the vacuum pump 8. The first water pump 10 is installed on the water tank 9 and connected to the water tank 9. The water tank 9 is placed next to the rack 01, and the transfer box 11 is connected to a pumping pipe 15, which is connected to the first On the water pump 10, the water tank 9 is connected to a water outlet pipe 16 installed on the frame 01, and the water outlet pipe 16 can be removed from the frame 01 as needed. An ultrafiltration membrane 39 is detachably connected in the water tank 9. The pore size of the ultrafiltration membrane 39 is selected to be between 1 nanometer and 10 nanometers so that impurities such as bean gum and starch in the water entering the water tank 9 can be retained on the ultrafiltration membrane 39. The ultrafiltration membrane 39 divides the internal space of the water tank 9 into a filtration area 901 and a water outlet area 902. The first water pump 10 is connected to the filtration area 901, and a second water pump 40 connected to the water outlet area 902 is installed on the water tank 9. The water outlet pipe 16 is connected to the second water pump 40, and the water outlet of the water outlet pipe 16 is connected to a nozzle 41, which corresponds to the outer wall of the sieve barrel 1.

[0026] Working principle: Figure 1As shown, the sealing plate 6 on the screen barrel 1 is opened, and the cooked beans are input into the screen barrel 1 from the feeding channel 5 by using a food pump in cooperation with the pipeline, and the sealing plate 6 is closed to close the feeding channel 5, and the first motor 4 works to drive the crushing blade 2 to rotate to beat the beans in the screen barrel 1 into a bean paste slurry with bean skins, and the sieve holes 101 on the screen barrel 1 retain the bean skins in the screen barrel 1 and make the bean paste slurry leak out of the sieve holes 101 and enter the sand washing box 7, and when the crushing blade 2 rotates, it drives the rolling roller 3 to roll on the inner wall of the screen barrel 1 to squeeze the bean paste out of the sieve holes 101, which is conducive to the bean paste entering the sand washing box 7 better, and at the same time, pouring clean water on the screen barrel 1 can dilute the bean paste slurry in the screen barrel 1, which helps the bean paste slurry with bean paste in the screen barrel 1 to enter the sand washing box 7 more smoothly, and flush the bean paste adhering to the outer wall of the screen barrel 1 into the sand washing box 7 reduces the loss of bean paste, and cooperates with the slow rotation of the screen barrel 1 to make it easier for the bean paste adhered to the outer wall of the screen barrel 1 to fall into the sand washing box 7, and the clean water also enters the sand washing box 7 to collect and dilute the bean paste slurry in the sand washing box 7, and facilitates the dissolution of the bean glue and starch in the bean paste slurry into the water, cooperates with the vacuum pump 8 to form a negative pressure in the main water pipe 14, so that the water in the bean paste slurry in the sand washing box 7 flows into the main water pipe 14 through the filter cloth 12 and the filter hole 13 and then enters the transfer box 11, and then the bean glue and starch dissolved in the water enter the transfer box 11 with the water. At this time, the bean paste is retained in the sand washing box 7 by the filter cloth 12, so that the bean paste and water in the bean paste slurry are separated and filtered, and as the filtration proceeds, the bean paste on the filter cloth 12 gradually dries, so that the dehydration of the bean paste is realized, the sand washing efficiency is improved, and it is beneficial to subsequent processing. The water in the transfer box 11 enters the filtering area 901 in the water tank 9 through the first water pump 10, and the bean glue, starch and other impurities in the water are filtered out by the ultrafiltration membrane 39 in the water tank 9 and enter the water outlet area 902, and is pumped into the outlet pipe 16 by the second water pump 40 and sprayed on the screen barrel 1 through the nozzle 41 on the outlet pipe 16, and is used as water for flushing the screen barrel 1 and diluting the bean paste slurry, so as to realize the recycling of water resources. The setting of the nozzle 41 increases the spraying range, and further facilitates the flushing of the bean paste adhered to the outer wall of the screen barrel 1. After all the bean paste slurry in the screen barrel 1 enters the sand washing box 7, the vacuum pump 8 is stopped, water is added to the sand washing box 7 and stirred, and then the vacuum pump 8 is started, so that the water in the sand washing box 7 is quickly separated from the bean paste and enters the transfer box 11 and is pumped into the water tank 9 through the first water pump 10 for filtration. The number of times of adding water to the sand washing box 7 is determined according to the needs, so that the second water pump 40 recycles the water filtered by the water outlet area 902 as water to be added to the sand washing box 7, and repeats the above operation to separate the bean paste and water, so that the bean paste remains on the filter cloth 12 in the sand washing box 7. There is no need to let it stand for sedimentation to separate the bean paste and water into layers and then discharge the upper water. The water can be directly separated from the bean paste, and the bean gum and starch dissolved in the water can be removed at the same time, thereby completing the operation of adding water to wash the sand for many times and quickly completing the separation of the bean paste and water. Finally, in order to remove part of the bean gum and starch in the bean paste slurry to improve the taste of the finished bean paste, when performing the sand washing operation of adding water for many times, the water for washing the sand can be recycled to avoid wasting water resources, and avoid the need for a lot of time for standing for sedimentation to separate the bean paste and water, resulting in low sand washing efficiency.
