Description

Technical Field

[0001] The present invention relates to the technical field of goat milk product processing, and in particular to a fermentation device and method for processing goat milk products. Background Art

[0002] Goat milk products refer to various products made from goat milk. Common goat milk products include goat milk, goat milk powder, yogurt, cheese, etc. Goat milk itself has rich nutritional value. Its protein, fat, vitamins and trace elements are higher than cow's milk, and its nutritional composition is closest to human milk. Therefore, it is known as the "king of milk".

[0003] For example, the Chinese patent publication number: CN222675393U discloses a fermentation device for processing goat milk products, comprising a base, a limiting ring fixedly installed on the top of the base, a fermentation tank placed on the inner side of the limiting ring, a cover plate placed on the top of the fermentation tank, and a motor fixedly installed on the top of the cover plate through a bracket. The present invention starts the motor and the heating strip, and the heating strip is started to heat the surface of the fermentation tank. At the same time, the motor starts to drive the rotating rod to rotate, and the rotation of the rotating rod drives multiple stirring blades to rotate. The rotation of the stirring blades can mix and stir the goat milk and additives inside the fermentation tank. At the same time, the rotation of the rotating rod can drive the reciprocating screw to rotate through the transmission wheel and the transmission belt. The rotation of the reciprocating screw drives the threaded sleeve to move back and forth up and down, the movement of the threaded sleeve drives the annular frame to move, and the movement of the annular frame drives the heating strip to move, thereby achieving the effect of uniformly heating the fermentation tank, effectively improving the fermentation efficiency.

[0004] At present, a fermentation device for processing goat milk products still has some shortcomings. For example, when in use, the stirring position of the stirring blade is fixed, and there are differences in concentration and temperature of goat milk at different heights and areas in the fermentation tank. The stirring blade only rotates on a fixed plane and cannot fully stir the upper and lower layers of materials, which can easily cause uneven mixing of the starter and goat milk, insufficient fermentation in some areas, affecting the quality stability of the final product and reducing the taste and nutritional value of the goat milk product. Summary of the Invention

[0005] In view of the deficiencies in the prior art, the present invention provides a fermentation device and method for processing goat milk products, which solve the problems.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] A fermentation device and method for processing goat milk products, comprising: a fermentation tank body, wherein the bottom surface of the fermentation tank body is provided with a support plate, a plurality of bases are fixedly installed on the bottom surface of the fermentation tank body, the bases are fixedly connected to the support plate, and an inner liner is provided inside the fermentation tank body; a mounting bracket is fixedly installed on the top surface of the fermentation tank body, a hollow shaft drive motor is fixedly installed on the top surface of the mounting bracket, a rotating hole is opened on the top surface of the fermentation tank body, a hollow rotating rod is rotatably installed inside the rotating hole, the hollow rotating rod is fixedly connected to the shaft of the hollow shaft drive motor, and a plurality of stirring blades are provided on the outside of the hollow rotating rod; a telescopic assembly, wherein the telescopic assembly is arranged inside the hollow rotating rod and is used to drive the stirring blade to move up and down.

[0008] By adopting the above technical solution, a hollow rotating rod is set up, and after the hollow shaft driving motor is energized, the shaft of the motor starts to rotate, and the hollow rotating rod rotates along with the rotation of the motor shaft. As the hollow rotating rod rotates, the stirring blades installed on the outside of the hollow rotating rod also start to rotate. The stirring blades stir the materials (such as goat milk and starter) in the inner tank of the fermentation tank, so that the goat milk and the starter are fully mixed, thereby promoting the fermentation reaction, improving the fermentation efficiency and fermentation quality, making the fermentation process more complete and stable, and improving the quality of goat milk products.

[0009] Preferably, the telescopic assembly includes: an air inlet hole, which is provided on the outer circular wall of the hollow rotating rod, an air inlet pipe is provided on the internal fixed sleeve of the air inlet hole, and the air inlet pipe passes through the shaft of the hollow shaft drive motor, an air pumping box is fixedly installed on the top surface of the fermentation tank body, and the air pumping box is connected to the air inlet pipe, a telescopic rod is provided inside the hollow rotating rod, a telescopic hole is provided on the inner bottom surface of the hollow rotating rod, the telescopic rod passes through the telescopic hole and extends to the outside, a connecting ring is provided on the external fixed sleeve of the telescopic rod, a piston block is fixedly installed on the top surface of the telescopic rod, and a spring is provided on the outside of the telescopic rod.

[0010] By adopting the above technical solution and setting a telescopic rod, the gas in the air box enters the hollow rotating rod through the air inlet pipe, and the gas entering the hollow rotating rod pushes the piston block. The piston block is fixed on the top surface of the telescopic rod, so the movement of the piston block drives the telescopic rod to move. The spring is set on the outside of the telescopic rod. When the gas pushes the telescopic rod to move, the spring is compressed. When the gas pressure changes, the spring can assist the telescopic rod to reset, thereby achieving more comprehensive stirring of the materials in the inner liner of the fermentation tank, improving the mixing uniformity of goat milk and materials such as starter, thereby improving fermentation efficiency and fermentation quality, and helping to obtain better quality goat milk products.

[0011] Preferably, the air pumping box is movably provided with an air pumping plate inside, the top surface of the air pumping plate is provided with a one-way valve, the bottom surface of the air pumping box is provided with a movable hole, the bottom surface of the air pumping plate is fixedly installed with a threaded rod, the threaded rod passes through the movable hole and extends to the outside, the top surface of the fermentation tank body is rotatably installed with a threaded cylinder, the external fixed sleeve of the hollow shaft driving motor shaft is provided with a first pulley, the external fixed sleeve of the threaded cylinder is provided with a second pulley, the outside of the first pulley and the second pulley are provided with belts, and the threaded cylinder is threadedly connected to the threaded rod.

[0012] By adopting the above technical solution, a threaded rod is set, and when the hollow shaft drives the motor to work, its shaft rotates, and the first pulley fixed on the outside of the shaft rotates accordingly. Through the belt, power is transmitted to the second pulley fixed on the outside of the threaded cylinder, thereby driving the threaded cylinder to rotate. When the threaded cylinder rotates, the threaded rod moves up and down in the movable hole, driving the air pumping plate to make up and down reciprocating motion in the air pumping box. When the air pumping plate moves upward in the air pumping box, the air pressure above the air pumping plate decreases, the one-way valve opens, and gas enters the air pumping box from the outside; when the air pumping plate moves downward, the air pressure above the air pumping plate increases, the one-way valve closes, and the gas in the air pumping box enters the hollow rotating rod under the action of pressure. The use of belt drive and thread drive reduces the demand for additional power sources, improves power utilization, and reduces the energy consumption of the equipment.

[0013] Preferably, two limiting grooves are provided on the outside of the hollow rotating rod, and the stirring blades are movably sleeved in the limiting grooves.

[0014] By adopting the above technical solution and setting a limit groove, the stirring blade can move up and down along the limit groove while rotating with the hollow rotating rod. The limit groove plays a role in positioning and guiding the stirring blade, so that the stirring blade always remains on the predetermined track during the movement, reducing the shaking and collision of the stirring blade during movement and extending the service life of the stirring blade.

[0015] Preferably, a heating ring is provided inside the fermentation tank body, a plurality of heating holes are provided on the top surface of the heating ring, an electric heating rod is provided inside the heating hole, an inspection hole is provided on the outer circular wall surface of the fermentation tank body, a temperature sensor is provided inside the inspection hole, a temperature controller is fixedly installed on the outer circular wall surface of the fermentation tank body, and the temperature sensor is electrically connected to the temperature controller and the electric heating rod.

[0016] By adopting the above technical solution, a temperature sensor is set up, which detects the temperature inside the fermentation tank body in real time and converts the temperature signal into an electrical signal to transmit to the temperature controller. The temperature controller receives the signal from the temperature sensor and compares it with the preset fermentation temperature range. If the actual temperature is lower than the set value, the temperature controller activates the electric heating rod to increase the temperature inside the tank through the heat generated by the heating rod. If the actual temperature reaches or exceeds the set value, the temperature controller cuts off the power supply of the electric heating rod and stops heating. The heating ring surrounds the inside of the fermentation tank body. The distribution of multiple heating holes and electric heating rods ensures uniform heat diffusion, avoids local temperature differences, and meets the strict temperature requirements of different fermentation stages.

[0017] Preferably, a sealing ring is fixedly adhered to the inner circular wall surface of the telescopic hole.

[0018] By adopting the above technical solution and setting a sealing ring, when the gas generated by the air box pushes the piston block and the telescopic rod to move, the sealing ring can effectively seal the gap between the telescopic hole and the telescopic rod to prevent gas leakage from the gap.

[0019] Preferably, a discharge pipe is provided on the bottom surface of the fermentation tank body, and a solenoid valve is provided on the outside of the discharge pipe.

[0020] By adopting the above technical solution and setting up a solenoid valve, the solenoid valve can be quickly opened or closed by an electric control signal, thereby realizing precise control of the on and off of the discharge pipe.

[0021] Preferably, an observation window is provided on the outside of the fermentation tank body.

[0022] By adopting the above technical solution and setting up an observation window, the operator does not need to open the fermentation tank. Instead, he can visually check the fermentation status of the goat milk inside the fermentation tank body through the observation window, such as the color change of the fermentation liquid, whether bubbles are generated, the stirring status of the material, etc. If any abnormality occurs, measures can be taken quickly to adjust it to avoid losses caused by fermentation failure.

[0023] A fermentation method for processing goat milk products, applicable to any of the above-mentioned fermentation devices for processing goat milk products, is characterized by the following specific steps:

[0024] Step 1: Raw material pretreatment: Select fresh high-quality goat milk raw materials, filter and sterilize them to remove impurities and harmful microorganisms to ensure the purity and sterility of the raw materials. The pretreated goat milk is transported to the inner tank of the fermentation tank through the feed port;

[0025] Step 2: Temperature control: According to the process requirements of goat milk product fermentation, the target fermentation temperature is set on the temperature controller. The temperature sensor monitors the internal temperature of the fermentation tank in real time. When the temperature is lower than the set value, the temperature controller automatically starts the electric heating rod to heat the goat milk through the heating holes on the heating ring; when the temperature reaches the set value, the electric heating rod stops working to keep the temperature stable;

[0026] Step 3: Stirring operation: start the hollow shaft drive motor to drive the hollow rotating rod to rotate, so that the stirring blades can perform preliminary stirring on the goat milk to promote uniform mixing of the goat milk and the starter;

[0027] Step 4: The air pumping plate in the air pumping box moves, pressing air into the hollow rotating rod through the air inlet pipe and the air inlet hole. The gas pushes the piston block, causing the telescopic rod to move downward, driving the stirring blade to move downward along the limit groove, realizing the up and down movement of the stirring blade, enhancing the stirring effect and promoting uniform fermentation.

[0028] Step 5: Fermentation termination judgment: when the fermentation time reaches the time set by the process, or when the goat milk product is observed through the observation window, the fermentation is judged to be complete.

[0029] In summary, the present invention mainly has the following beneficial effects:

[0030] By setting a telescopic rod, the gas in the air box enters the hollow rotating rod through the air inlet pipe. The gas entering the hollow rotating rod pushes the piston block. The piston block is fixed on the top surface of the telescopic rod, so the movement of the piston block drives the telescopic rod to move. The spring is set on the outside of the telescopic rod. When the gas pushes the telescopic rod to move, the spring is compressed. When the gas pressure changes, the spring can assist the telescopic rod to reset, thereby achieving more comprehensive stirring of the materials in the inner liner of the fermentation tank, improving the mixing uniformity of goat milk and starter agents and other materials, thereby improving fermentation efficiency and fermentation quality, and helping to obtain better quality goat milk products.

[0031] By setting a threaded rod, when the hollow shaft drives the motor to work, its shaft rotates, and the first pulley fixed on the outside of the shaft rotates accordingly. Through the belt, power is transmitted to the second pulley fixed on the outside of the threaded cylinder, thereby driving the threaded cylinder to rotate. When the threaded cylinder rotates, the threaded rod moves up and down in the movable hole, driving the air pumping plate to make up and down reciprocating motion in the air pumping box. When the air pumping plate moves upward in the air pumping box, the air pressure above the air pumping plate decreases, the one-way valve opens, and gas enters the air pumping box from the outside; when the air pumping plate moves downward, the air pressure above the air pumping plate increases, the one-way valve closes, and the gas in the air pumping box enters the hollow rotating rod under the action of pressure. The use of belt drive and thread drive reduces the demand for additional power sources, improves power utilization, and reduces the energy consumption of equipment. BRIEF DESCRIPTION OF THE DRAWINGS

As the hollow rotating rod 8 rotates, the stirring blades 9 installed on the outside of the hollow rotating rod 8 also start to rotate. The stirring blades 9 stir the materials (such as goat milk and starter) in the inner tank 4 of the fermentation tank, so that the goat milk and starter are fully mixed, which promotes the fermentation reaction, improves the fermentation efficiency and fermentation quality, makes the fermentation process more sufficient and stable, and improves the quality of goat milk products.

When the gas pressure changes, the spring 34 can assist the telescopic rod 13 to reset.
