Description

Technical Field

[0001] The utility model relates to the technical field of stinky tofu brining, in particular to an energy-saving stinky tofu brining device. Background Technique

[0002] Changsha stinky tofu belongs to the slightly fermented type of stinky tofu. Its production process is that the tofu is not fermented, but the brine is fermented, and then the tofu is immersed in the brine for a period of time to be processed into stinky tofu. When fried and eaten, stinky tofu has a unique flavor of "smelling stinky but tasting delicious".

[0003] The stinky brine is one of the core keys to making stinky tofu and cannot be eaten directly. It is generally used to ferment tofu and its related food raw materials to form special stinky foods. However, there are many problems in the fermentation and use process of traditional brine. One of the more important problems is due to the brining temperature. In the prior art, in order to shorten the brining time, the brine is heated. For example, CN210620825U discloses a device for promoting the accelerated fermentation of stinky tofu brine, including a brining machine, the brining machine is connected with a heating device for heating the brine and a circulating device for updating the brine; the heating device includes a hot water circulation coil arranged in the brining machine, the hot water circulation coil is connected with a hot water heating tank, wherein, a connecting bracket is arranged between the hot water circulation coil and the bottom of the brining machine, the hot water circulation coil is a vertical annular basket, and the hot water circulation coil is arranged close to the side wall of the brining machine; the water inlet end of the circulating device is communicated with the bottom of the brining machine, and the water outlet end is communicated with the brining machine. During the use of this device, the condensed water generated by the hot water heating tank is directly discharged, resulting in waste of resources and increasing the production cost of stinky tofu. Therefore, it is urgent to improve the existing device for accelerating the fermentation of stinky tofu brine to further reduce the waste of resources such as water and steam during the stinky tofu brining process. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an energy-saving stinky tofu brining device with a simple structure and capable of effectively reducing the production cost of stinky tofu.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] An energy-saving stinky tofu brining device, including a brining machine and a spraying device. The brining machine is connected with a heating device for heating the brine and a circulating device for renewing the brine. The heating device includes a hot water circulation coil and a hot water tank arranged in the brining machine. The water inlet end and the water outlet end of the hot water circulation coil are respectively connected with the water outlet pipe and the water return pipe of the hot water tank. The condensate overflow pipe of the hot water tank is communicated with the main spraying water supply pipe, and the water outlet end of the main spraying water supply pipe is connected with the water inlet of the spraying device. The spraying device is arranged on the spraying section of the brining machine and the drying pool, and is used for cleaning the stinky tofu after brining. The water inlet end of the circulating device is communicated with the bottom brine discharge pipe of the brining machine, and its water outlet end is communicated with the brine inlet pipe of the brining machine.

[0007] The main spraying water supply pipe extends along the inner side wall of the brining machine to the lower part of the spraying device. The outer side wall of the main spraying water supply pipe exposed in the air is coated with a heat insulation layer, which reduces the heat loss when the condensate flows through the main spraying water supply pipe. At the same time, the hot water in the main spraying water supply pipe can further play a role in heating or keeping warm the brine.

[0008] The brining machine includes a feeding section, a brining pool, a spraying section, a drying pool and a discharging section connected in sequence, and a conveyor belt for conveying stinky tofu arranged in each section. A water receiving tray is arranged under the conveyor belt in the feeding section. A plurality of temperature control probes are arranged in the brining pool, and the temperature control probes are electrically connected with a PLC controller. At least two first spraying devices are arranged at intervals on the spraying section. A second spraying device and a bubbling device are arranged near the discharging section of the drying pool. A water receiving and collecting box is arranged between the spraying section and the drying pool.

[0009] The water inlet pipes of the first spraying device and the second spraying device are communicated with the main spraying water supply pipe through a spraying branch pipe with a three-way joint or a connector.

[0010] Both the first spraying device and the second spraying device include a water collecting tank and a spraying guide plate arranged on one side of the water collecting tank. An inlet for communicating with the main spraying water supply pipe is arranged on one side of the water collecting tank.

[0011] The cross section of the spraying guide plate is in an S shape, so that the spraying water in the water collecting tank forms a waterfall-like water flow after flowing out along the spraying guide plate, improving the cleaning effect of the brine on the surface of the stinky tofu.

[0012] The hot water tank includes a tank body, a steam pipe, a water outlet pipe, a water return pipe, a water inlet pipe, and a condensate overflow pipe. The steam pipe is connected to the bottom of the tank body and is located below the water outlet pipe and the water return pipe. The water inlet pipe is arranged at the top of the hot water tank. The condensate overflow pipe is arranged on one side above the water outlet tank. A temperature sensor is arranged inside the hot water tank. Electromagnetic control valves are arranged on the steam pipe, the water outlet pipe, the water return pipe, the water inlet pipe, and the condensate overflow pipe. The temperature sensor and the electromagnetic control valves are electrically connected to a PLC controller. By comparing the temperature detected by the temperature control probe and the temperature sensor received by the PLC controller with the set temperature, and then regulating the electromagnetic control valves on the steam pipe, the water outlet pipe, the water return pipe, the water inlet pipe, and the condensate overflow pipe, the temperature of the brine in the marinating machine can be accurately controlled.

[0013] The circulation device includes a fermentation tank. The water inlet end of the fermentation tank is connected to the brine discharge pipe of the marinating machine through a brine pumping pump, and the water outlet end is connected to the brine inlet pipe of the marinating machine.

[0014] The beneficial effects of the energy-saving stinky tofu marinating device of the present utility model:

[0015] The energy-saving stinky tofu marinating device uses a heating device to heat the brine of the marinating machine, and uses the hot water flowing out from the condensate overflow pipe of the hot water tank for the spray cleaning of the stinky tofu after marinating. It can not only reduce the waste caused by the overflow of condensate water in the hot water tank and reduce the water consumption of the spray device after marinating the stinky tofu, but also further maintain the temperature of the brine in the marinating machine, reduce the temperature difference between the stinky tofu after spray water bath marinating, and thus improve the quality of the stinky tofu.

[0016] At the same time, the hot water circulation coil of the heating device can quickly increase the temperature of the brine. In daily use, the temperature of the hot water tank can be set to 55°C. After the water temperature in the tank reaches the specified temperature, the valve is opened. During and after the use of the brine, it can always maintain 37°C, reducing the marinating time. It can make the marinating time in winter the same as that in summer, shortening by one hour, and at the same time reducing the rest time, from the previous 6 hours of rest to the current 1 hour.
