Box tofu filling system and method

Abstract

The invention discloses a box tofu filling system and method. The box tofu filling system comprises a tofu box conveying belt. The conveying belt is sequentially provided with tofu box containing grooves, and a primary soybean milk filling section for injecting soybean milk into tofu boxes, a soybean milk supplementing section and a sealing section are sequentially arranged front and back along the tofu box conveying belt, and the conveying belt carries the tofu boxes to continuously pass through the primary soybean milk filling section, the soybean milk supplementing section and the sealing section at the constant speed, and for a soybean milk supplementing nozzle of the soybean milk supplementing section, a soybean milk supplementing control device is used for controlling opening and closing of the soybean milk supplementing nozzle. Laser liquid level sensors are arranged on the two sides of the production line tofu boxes, non-contact liquid level measurement soybean milk supplementing is achieved, and the problem about cross contamination is solved; the measuring precision of the liquid level sensors is improved, soybean milk filling is not achieved through one-time filling while the secondary soybean milk supplementing manner is adopted, and the soybean milk is prevented from overflowing out of the boxes while it is guaranteed that the boxes are full.

Description

technical field [0001] The invention relates to the technical field of tofu industrial production, in particular to a box tofu filling system and a method thereof. Background technique [0002] At present, due to the inaccurate filling liquid level of the domestic production box tofu filling equipment, there is a situation that the box cannot be fully filled. The solution in actual production is to take excessive grouting, let the soybean milk overflow the outside of the box to ensure that it is full. However, the soy milk that overflows out of the box is collected and used again, which will greatly increase the risk of contamination of subsequent products. Japanese equipment uses an electrode sensor to determine the grouting liquid level, and when the liquid level reaches the preset height, it will automatically stop filling and realize one-time filling. However, in this technical solution, a pair of electrodes used to control the liquid level will be in contact with each...

Problems solved by technology

[0003] The purpose of the present invention is to provide a box tofu filling system and its method. Secondary grout replenishment is adopted, and laser liquid level sensors are arranged on both sides of the tofu box on the conveyor belt to achieve non-contact liquid level measurement and precise grout replenishment, which solves the problem of Eliminate the problem of cross-contamination and improve filling efficiency
