Embodiment 1

[0020] A box tofu filling system, such as figure 1 with figure 2 As shown, the system includes a frame 1, on which a bean curd box conveyor belt 2 is arranged, and the conveyor belt 2 is driven by chain shafts at both ends, and the tofu box placement slots 3 are sequentially arranged on the conveyor belt 2. A primary grouting section 5, a grout filling section 6 and a sealing section 7 for pouring soybean milk into the tofu box 4 are provided, and the conveyor belt carries the tofu box 4 through the primary grouting section 5, the grout filling section 6 and the sealing section 7 continuously and at a constant speed. , the soybean milk poured into the tofu box 4 by the grouting nozzle in the primary grouting section 5 is not full of the tofu box, and the grout filling nozzle in the grouting section 6 pours soybean milk into the tofu box 4 moved from the primary grouting section 5 to fill the tofu box , and then the tofu box 4 full of soy milk is sealed by the sealing section...

Embodiment 2

[0034] A box of bean curd filling method, this embodiment is based on the method of the embodiment 1 system, so the structural features described in embodiment 1 are applicable to this embodiment, and if any structures involved in this embodiment are not included in embodiment 1 The related content is also applicable to embodiment 1. The method includes primary grouting and secondary grouting, wherein the primary grouting is to pour soybean milk into an empty tofu box carried on a tofu box conveyor belt, and the level of the injected soybean milk is lower than that of a full box of soybean milk, Usually it is 10 to 15 mm lower than the full box state, and the secondary grouting is to continue grouting to the bean curd box that is conveyed from the conveyor belt and through the primary grouting to supplement the soymilk.

[0035] Wherein: the primary grouting adopts the grouting method of timing quantitative pump, and the flow of the quantitative pump is controlled by adjusting...

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...
