[0002] Sodium metabisulfite is a commonly used food additive in the processing of pickled bamboo shoots. It has multiple functions such as color protection and anti-oxidation. It plays an outstanding role in maintaining the color of pickled bamboo shoots and inhibiting the fibrosis of pickled bamboo shoots. The "National Food Safety Standard for the Use of Food Additives" (GB 2760-2014) stipulates that the residual sulfur dioxide in the final product shall not exceed 0.1g / Kg, so in order to process semi-finished products into finished products, they must be desulfurized to reduce the residual sulfur dioxide and meet the safety standards.

DETAILED DESCRIPTION

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with specific implementation methods.

[0026] like Figure 1As shown, a processing system for pickled bamboo shoots includes a desulfurization pool 100, a pre-cooking pot 200, and a cooling pool 300 which are sequentially arranged along the production line; a warm water drain port 1 is provided at the end of the desulfurization pool 100 to allow the water entering the desulfurization pool 100 to flow; a cold water inlet 2 is provided in the cooling pool 300, and a circulation mechanism is provided between the desulfurization pool 100 and the cooling pool 300.

[0027] In this embodiment, the desulfurization pool 100 uses the fluidity of warm water to clean the pickled bamboo shoots placed therein, thereby achieving the purpose of cleaning and desulfurization; then the pre-cooking pot 200 is used for aging, and in this process, the pickled bamboo shoots can be further desulfurized; finally, the aging pickled bamboo shoots are placed in the cooling pool 300 to quickly cool the pickled bamboo shoots, and in this process, since the cold water in the cooling pool 300 can be heated, in other words, the cooling pool 300 is used to quickly cool the pickled bamboo shoots, which can heat up the cold water, so the circulation mechanism drives the heated water to the desulfurization pool 100 to achieve water saving, so there is no need to set up additional heating equipment, thereby meeting the energy saving requirements well. Since the water can flow back to the desulfurization pool 100 through the circulation mechanism, the water in the cooling pool 300 also has fluidity, thereby further achieving the desulfurization of the pickled bamboo shoots.

[0028] In order to further increase the desulfurization speed of the pickled bamboo shoots in the desulfurization tank 100, a pneumatic mechanism is provided in the desulfurization tank 100. Specifically, the pneumatic mechanism includes a pneumatic tube 3 and an air pump 4 arranged along the extension direction of the desulfurization tank 100; the pneumatic tube 3 is provided with a plurality of air holes; the air pump 4 is used to send gas into the pneumatic tube 3. The extension direction of the desulfurization tank 100 is the flow direction of the warm water in the desulfurization tank 100. In this direction, the pickled bamboo shoots move along the flow direction of the warm water due to the fluidity of the warm water, so that on this flow path, the pickled bamboo shoots are continuously and efficiently tumbled by exhausting the pneumatic tube 3, thereby improving the desulfurization efficiency. Therefore, in the desulfurization tank 100, the combination of warm water and pneumatic tumbling can quickly withdraw sulfur dioxide from the pickled bamboo shoots. Further, a plurality of pneumatic tubes 3 are arranged side by side. That is to say, the pores substantially cover the desulfurization tank 100 , so that continuous and efficient tumbling of the pickled bamboo shoots can be achieved at various positions of the desulfurization tank 100 .

[0029] In this embodiment, a pasteurization device 5 is also included, which is used to sterilize pickled bamboo shoots and produce warm water; the circulation mechanism drives the warm water produced by the pasteurization device 5 to the desulfurization tank 100. When the pasteurization device 5 sterilizes the pickled bamboo shoots, warm water will be produced in its cooling part. The temperature of the warm water meets the use temperature of the warm water in the desulfurization tank 100, so it can be used directly. Its energy-saving principle is similar to that of cooling water, so it will not be repeated here.

[0030] Furthermore, the temperature of the water entering the desulfurization tank 100 is 30-50° C. That is, the water driven by the circulation mechanism has a temperature of 30-50° C. before entering the desulfurization tank 100. Compared with cold water, it can effectively provide molecular mobility, thereby increasing the desulfurization speed. At the same time, water at this temperature is easy to obtain, and it can also avoid adding a heating device to increase energy costs.

[0031] In this embodiment, the circulation mechanism includes a first pipeline 6, a second pipeline 7, a third pipeline 8 and a water pump 9; the first pipeline 6 is connected to the cooling pool 300; the second pipeline 7 is connected to the pasteurization equipment 5; the third pipeline 8 is connected to the desulfurization pool 100; the inlet end of the water pump 9 is connected to the first pipeline 6 and the second pipeline 7, and the outlet end of the water pump 9 is connected to the third pipeline 8. Specifically, the first pipeline 6 is connected to the water outlet 10 at the end of the cooling pool 300, the second pipeline 7 is connected to the cooling part of the pasteurization equipment 5, and the third pipeline 8 is connected to the warm water inlet 11 of the desulfurization pool 100. Therefore, the water pump 9 can pump the warm water generated in the cooling pool 300 and the pasteurization equipment 5 into the desulfurization pool 100 through the third pipeline 8, thereby effectively improving the desulfurization efficiency of pickled bamboo shoots on the basis of energy and water saving.

[0032] In this embodiment, the head end of the desulfurization tank 100 is provided with a warm water inlet 11, and the warm water inlet 11 is provided with a first valve; the warm water outlet 1 is provided with a second valve. Further, the flow rate of water passing through the first valve and the flow rate of water passing through the second valve are consistent. In addition, in order to keep the above-mentioned flow rate consistent, the first valve and the second valve are both equipped with flow sensors. It is known that the flow diameter of the first valve and the second valve is consistent, and the opening is adjustable, and this embodiment is equipped with a control system, such as a computer, PLC, etc. Therefore, after the flow sensor feeds back the instantaneous flow data to the control system, after comparison by the control system, the opening of the first valve and the second valve can be adjusted in real time, so as to keep the water flow rate balanced, and at the same time, it also avoids the desulfurization tank 100 overflowing due to fast water inflow and slow water outflow, and also avoids the desulfurization tank 100 failing to meet the continuous production requirements due to slow water inflow and fast water outflow.

[0033] Therefore, this embodiment has a reasonable design, simple structure, and is easy to use. It overcomes the shortcomings of low production efficiency and / or large water consumption of traditional desulfurization methods. Compared with the desulfurization time of up to 2 to 3 days in the current prior art, this embodiment only takes 2 to 3 hours to meet the national standard residual sulfur requirements. When the present embodiment is used in detail, firstly, warm water of 30-50° C. is injected into the desulfurization tank 100. In the case of continuous production, the warm water formed by the cooling tank 300 and / or the warm water formed by the pasteurization equipment 5 are fully utilized. It is known that in the initial use, only the warm water formed by the pasteurization equipment 5 can be used. After a period of desulfurization process, the warm water formed by the cooling tank 300 can be used. Then, the pickled bamboo shoots after washing and cutting are poured into the desulfurization tank 100, and the air pump 4 is turned on to let the pickled bamboo shoots tumble in the desulfurization tank 100. After a period of time, the first valve and the second valve are opened synchronously to keep the flow rate consistent. After the desulfurization in the desulfurization tank 100 is completed, the pickled bamboo shoots are fished out and placed in the pre-cooking pot 200 for cooking and maturation. Finally, the cooked pickled bamboo shoots are quickly fished into the cooling tank 300 for cooling, and the cooled pickled bamboo shoots can be put into subsequent production.

[0034] The above are only preferred embodiments of the present invention. It should be noted that the above preferred embodiments should not be regarded as limiting the present invention. The protection scope of the present invention should be based on the scope defined by the claims. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the spirit and scope of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
