Description

Technical Field

[0001] The invention relates to the technical field of fresh beer brewing, and more specifically to intelligent fresh beer brewing equipment. Background Art

[0002] When freshly brewed beer is processed, raw materials such as malt, rice, and corn are crushed for gelatinization and saccharification. The enzyme in the malt is used to hydrolyze the starch in the raw materials into sugars such as maltose, and the protein is decomposed into nutrients such as amino acids that are easy for yeast to ferment and utilize. After saccharification, the saccharified mash is pumped to the filter to separate the wort from the spent grains, and the clarified wort is boiled and cooled. The composition of the wort is stabilized and the aroma, bitterness and various effective ingredients of the hops are dissolved in the wort. Among them, the cooling process takes a long time. Since the shelf life of freshly brewed beer is short, the processing time should also be paid attention to, and the cooling time should be reduced as much as possible. The wort temperature can be lowered by refrigeration, but too low a temperature will destroy the taste of the wort. This is because the cooling step is before fermentation, and the wort temperature during fermentation should not be too low. Summary of the invention

DETAILED DESCRIPTION

[0026] An intelligent beer brewing equipment, such as Figures 1 to 6 As shown, it includes an outer bucket 1-1, and the inner diameter of the outer bucket 1-1 gradually increases from bottom to top until it remains unchanged, so that the upper part is a cylindrical thin wall. The upper end of the outer bucket 1-1 is fixedly connected to a connecting frame 1-2, and a shaft 1-3 is rotatably connected to the connecting frame 1-2, and the shaft 1-3 coincides with the axis of the outer bucket 1-1. A pulsator 1-4 is fixedly connected to the bottom of the shaft 1-3, and there is a gap between the pulsator 1-4 and the lower opening of the outer bucket 1-1. A fermentation tank 3-1 is arranged directly below the outer bucket 1-1, and a lid 3-3 is detachably connected to the fermentation tank 3-1. A driving mechanism is fixedly connected to the connecting frame 1-2, and the driving mechanism includes a first motor fixedly connected to the connecting frame 1-2, and the output shaft of the first motor is fixedly connected to the shaft 1-3 and arranged coaxially; or, the driving mechanism includes a first motor fixedly connected to the outside of the outer bucket 1-1, and the output shaft of the first motor and the top of the shaft 1-3 are synchronously driven through a pulley belt assembly. The driving shaft 1-3 rotates, driving the impeller 1-4 to rotate.

[0027] During operation, the boiled wort is injected into the outer bucket 1-1, and the liquid level is not higher than the bottom of the cylindrical thin wall. The outflow amount flowing out of the outer bucket 1-1 is much less than the injection amount, so that the impeller 1-4 rotates and the wort in the outer bucket 1-1 is rotated, so that the liquid level of the outer circle of the wort rises and the liquid level of the inner circle of the wort drops, thereby increasing the surface area and flow speed of the wort and the air, and accelerating the cooling speed of the wort in a gentle way.

[0028] It is further explained that the bottom of the outer bucket 1-1 is fixedly connected to the tail of the arc structure, the bottom of the arc structure extends downward, and the waterfall liquid outlet 1-6 is fixedly connected and connected to the lower end of the arc structure, so that the wort falls downward in a waterfall manner, increasing the contact area with the air, and further accelerating the cooling speed of the wort in a gentle way.

[0029] Preferably, a window is provided at the center of the lid 3-3, and the bottom of the waterfall-type liquid outlet 1-6 is located in the window, so that the wort flowing down in the waterfall passes through the window and enters the fermentation tank 3-1. The lid 3-3 is fixedly connected to the telescopic end of the electric telescopic rod 3-2 with the telescopic end facing upward, so as to adjust the height of the lid 3-3. When the lid 3-3 is raised, it is close to the waterfall-type liquid outlet 1-6, which is conducive to the wort passing through the window. When the lid 3-3 is lowered, it is pressed on the top of the fermentation tank 3-1 to complete the closure of the fermentation tank 3-1. A transparent cover is inserted at the window to close the window and realize the opening and closing of the window. The fermentation inside the fermentation tank 3-1 can also be observed. The heating method of the fermentation tank 3-1 can be achieved by heating the internal electric heating element.

[0030] The lower end of the outer bucket 1-1 is fixed with heat dissipation fins 1-7 evenly distributed from left to right. Any two adjacent heat dissipation fins 1-7 form a front-to-back airway. The number of waterfall-type liquid outlets 1-6 can be multiple and evenly distributed in the left and right directions. Each waterfall-type liquid outlet 1-6 corresponds to an airway, so that the waterfall-type liquid outlet 1-6 is in the airway. The bottom of the heat dissipation fins 1-7 is located at the waterfall-type liquid outlet 1-6. In addition, in combination with Figure 7 and 8 , at the rear side of the outer bucket 1-1, the front end of the fan blade frame 2-1 is fixedly connected with a drainage cover 2-2 covering the rear parts of all the heat dissipation fins 1-7, the drainage cover 2-2 is connected front and back, the rear end of the fan blade frame 2-1 is fixedly connected with a second motor 2-3, the output shaft of the second motor 2-3 is located in the fan blade frame 2-1, the output shaft of the second motor 2-3 is fixedly connected with blades 2-4 evenly distributed around the circumference, the upper end of the drainage cover 2-2 is fixedly connected and connected with one end of the drainage pipe 2-5, and the other end of the drainage pipe 2-5 is located just above the inner wall 1-5. After the second motor 2-3 is started, the fan blades 2-4 generate an airflow from back to front, entering all the airways, and dissipating the wort flowing down in a waterfall, while also dissipating the heat dissipation fins 1-7 and the waterfall liquid outlet 1-6, thereby also cooling the outer bucket 1-1. The wort is dissipated under the flow of room temperature airflow. On the other hand, the drainage pipe 2-5 directly dissipates heat to the wort inside the outer bucket 1-1.

[0031] Preferably, the top of the cover 3-3 after being raised fits with the lower end surface of the heat dissipation fin 1-7, thereby closing the bottom of the airway, so that the airflow can pass quickly back and forth without generating turbulence.

[0032] Furthermore, an inner wall 1-5 is fixedly connected to the connecting frame 1-2, and the inner wall 1-5 is located in the outer bucket 1-1. The upper part of the outer bucket 1-1 is a cylindrical wall extending upward, and the lower end surface of the inner wall 1-5 coincides with the lower end surface of the cylindrical wall. The inner diameter of the outer bucket 1-1 increases from bottom to top before reaching the cylindrical wall, and the impeller 1-4 is located at the bottom opening of the outer bucket 1-1. The outer bucket 1-1, the shaft 1-3, the impeller 1-4 and the inner wall 1-5 are all coaxially arranged, so that when the wort flows in the outer bucket 1-1, the part where the liquid level rises is between the outer bucket 1-1 and the inner wall 1-5, and there is a gap between the lower end of the inner wall 1-5 and the upper end of the wort liquid level, and the airflow blows the upper center of the wort liquid level from the top of the inner wall 1-5, and then is diverted to the space between the outer bucket 1-1 and the inner wall 1-5 and then discharged. The flow channel has a high heat dissipation effect and does not generate turbulence.
