Detailed Description
To explain technical contents, structural features, achieved objects and effects of the invention in detail, the technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only a part of the embodiments of the present application, and not all embodiments. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a detailed description of various exemplary embodiments or implementations of the invention. However, various exemplary embodiments may be practiced without these specific details or with one or more equivalent arrangements. Moreover, the various exemplary embodiments may be different, but are not necessarily exclusive. For example, the particular shapes, configurations and characteristics of the exemplary embodiments may be used or implemented in another exemplary embodiment without departing from the inventive concept.
Fig. 1 shows a bean curd stick production unit 100 provided by the invention, and the bean curd stick production unit 100 adopts a solar power supply and carbon dioxide fluid heat supply mode to replace the traditional coal-fired heat supply mode to realize low-carbon and environment-friendly production of bean curd sticks. The bean curd stick production unit 100 comprises a carbon dioxide circulating system, a hot water supply system and a bean curd stick preparation system.
The bean curd stick preparation system comprises a bean soaking tank 31 for soaking soybeans, a crushing tower 32 for crushing the soybeans, a soybean milk cooking tank 33 for cooking the crushed beans into soybean milk, a forming tank 34 for performing a peeling forming process, a drying chamber 35 for drying bean curd sticks, and a humidifying chamber 36 for humidifying and softening the bean curd sticks. In the production process of the dried beancurd sticks, a bean soaking tank 31, a crushing tower 32, a soybean milk cooking tank 33, a forming tank 34, a drying chamber 35 and a humidifying chamber 36 are arranged from upstream to downstream in sequence. Wherein, the upper part of the humidifying chamber 36 is arranged with an atomizer 37 for atomizing hot water, the atomizer 37 is an ultrasonic atomizer.
The carbon dioxide circulation system comprises solar photovoltaic panels 1 for providing electrical energy, a carbon dioxide water source machine 12 for heating the carbon dioxide fluid, a digester heating pipe 13 and a heat exchanger 14. The solar photovoltaic panel 11 is electrically connected with the carbon dioxide water source machine 12 and transmits the electric power of the prepared high-temperature carbon dioxide fluid to the carbon dioxide water source machine. The heating pipe 13 of the soymilk boiling tank is coiled on the outer surface of the soymilk boiling tank 33 in a snake-shaped coiling way, and the arrangement way can reduce the temperature difference between the upper part and the lower part in the soymilk boiling tank 33 and improve the stability of the soybean milk in the soymilk boiling tank 33. In other embodiments, in order to further ensure the stability of power supply and avoid weather influence, a storage battery pack can be additionally arranged between the solar photovoltaic panel and the carbon dioxide water source machine to serve as a reserve power supply, or the carbon dioxide water source body is set to be in a double-line-incoming mode in which the solar photovoltaic panel and the mains supply power simultaneously.
The carbon dioxide water source machine 12, the heating pipe 13 of the pulp boiling tank and the heat exchange pipe 14 are sequentially communicated in fluid and form a loop for circulating carbon dioxide. When the unit 100 works, the high-temperature carbon dioxide fluid (the outlet temperature is controlled at 110 ℃ during the work) heated by the carbon dioxide water source machine 12 enters the heating pipe 13 of the soybean milk boiling tank to heat the soybeans in the soybean milk boiling tank 33. Thereafter, the carbon dioxide fluid exiting the digester 33 (temperature controlled at 100℃. during operation) enters the heat exchanger 14 to provide heat for the supply of hot water from the water softener 21 (see below). The carbon dioxide fluid in the heat exchanger 14 releases heat and is cooled and flows into the carbon dioxide water source machine 12 to complete a cycle.
The hot water supply system comprises a water softener 21 for receiving tap water, a heating pipe 22 for supplying hot water to flow, a heat storage tank 23 for storing the hot water, a three-way pipe 24 communicated with the heating pipe 22 and a purifying and recycling device 25 for purifying the hot water.
The water softener 21, the heat exchanger 14, the heating pipe 22 and the tee pipe 24 are in fluid communication in sequence, and the heat storage tank 23 is in fluid communication with the heating pipe 22 and is located upstream of the forming pond 34. The water softener 21 is located upstream of the heat exchanger 3 and serves to reduce calcium and magnesium ions in the water to reduce the hardness of the tap water. The hot water from the water softener 21 flows into the heat exchanger 3 and exchanges heat with the carbon dioxide fluid of the carbon dioxide circulation system, during which the temperature of the hot water rises (during operation, the outlet temperature is controlled at 95 ℃). Then, the hot water flowing out of the heat exchanger 14 flows into the heat storage tank 23, and the hot water of a stable temperature is continuously supplied to the downstream heat supply pipe 22 by the water storage and heat storage actions of the heat storage tank 23. The heating pipe 22 at the downstream of the heat storage box 23 passes through the forming tank 24 and the drying chamber 25 in sequence to provide heat for the forming tank and the drying chamber. In other embodiments, an electric heater may also be disposed within the heat storage tank 23 to further stabilize the temperature of the internal hot water supply.
Tee 24 is located downstream of drying chamber 35 and has a first water outlet conduit (not shown) in fluid communication with atomizer 37 of humidification chamber 36 for providing an atomized water source thereto, and a second water outlet conduit (not shown); the second water outlet pipeline is in fluid communication with the purification and recovery device 25, the water outlet end of the purification and recovery device 25 is in fluid communication with the water inlet end of the water softener 21, and the hot water in the branch is returned to the water softener 21 after impurities are removed by the purification and recovery device 25 so as to be recycled.
The working principle of the dried bean production unit 100 is explained as follows: soybeans are soaked in the soybean soaking tank 31 and crushed in the crushing tower 32, and then are cooked in the soybean cooking tank 33 to form soybean milk, and carbon dioxide fluid in the heating pipe 13 of the soybean cooking tank provides continuous and stable heating, so that the effect of slow stewing with slow fire is achieved, and other auxiliary materials do not need to be added into the soybean milk, and the taste of the soybean milk returns to the original taste.
And then, the soybean slurry enters a forming tank 34 to be subjected to a peeling forming process to prepare the dried beancurd sticks, and the dried beancurd sticks are dried in a drying chamber 35 and humidified and softened in a humidifying chamber 36 in sequence to be finally formed. Compared with the traditional process, the bean curd stick production unit 100 has high automation degree and low labor cost, provides the quality stability of the bean curd sticks and reduces the production cost of the bean curd sticks.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the foregoing description only for the purpose of illustrating the principles of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the invention as defined by the appended claims, specification, and equivalents thereof.
