DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] Embodiment 1

[0024] Reference Figure 1-3 A grinding device for malt powder fermentation comprises a grinding box 1 and a supporting leg 11 installed at the bottom of the grinding box 1, a material inlet 12 and a material outlet 13 are respectively arranged at the center of the upper and lower ends of the grinding box 1, a grinding chamber 101 is opened in the grinding box 1, a screening net 14 is detachably installed in the grinding chamber 101, a preliminary grinding component 2 for preliminary grinding is arranged above the screening net 14, a fine grinding component 3 for fine grinding is arranged below the screening net 14, a portable and detachable connection group 32 is arranged on the fine grinding component 3, and the bottom of the grinding box 1 is arranged in an arc shape.

[0025] Furthermore, the preliminary grinding assembly 2 includes a filling block 15 symmetrically installed in the upper half of the grinding chamber 101, a first motor 21 and two grinding rollers 22 rotatably installed between the two filling blocks 15, and a driving wheel 23 and a transmission wheel 24 are respectively installed on the two grinding rollers 22. The driving wheel 23 and the transmission wheel 24 are connected by a transmission belt 25, and the output connecting shaft of the first motor 21 is connected to the driving wheel 23.

[0026] It should be noted that a guide plate 121 is installed near the top of the grinding chamber 101 . The guide plate 121 is located at the bottom of the feed inlet 12 and has an arc shape.

[0027] The further advantage of adopting the above method is that after the malt enters the grinding chamber 101 through the feed port 12, the first motor 21 drives the driving wheel 23 and the transmission wheel 24 to rotate, thereby driving the two grinding rollers 22 to perform preliminary grinding on the malt, thereby improving the grinding efficiency, making the malt grinding more fine, and facilitating the later fermentation. The guide plate 121 guides the malt, and the arc setting can prevent the malt from falling to other places, thereby causing uneven grinding of some malt.

[0028] Embodiment 2 proposed based on Embodiment 1:

[0029] Reference Figure 1-5 The fine grinding assembly 3 includes a second motor 31, a connecting rod 33 and a grinding rod 34 installed at the bottom of the connecting rod 33. The second motor 31 is installed at the bottom of the screening net 14, and the output connecting shaft of the second motor 31 is connected to the connecting rod 33 through a connecting group 32. Grinding blocks 341 are equidistantly installed at the bottom of the grinding rod 34. The arc shape of the grinding rod 34 is the same as the arc shape of the inner wall of the grinding chamber 101 and is used in conjunction with it.

[0030] It should be noted that: the connection group 32 includes an upper assembly connection member 321 and a lower assembly connection member 322, and the lower assembly connection member 322 is connected to the upper assembly connection member 321 by being inserted into a slot on the upper assembly connection member 321; slide grooves 301 are equidistantly provided on the inner wall of the grinding chamber 101, and the screening net 14 can be detachably installed in the grinding chamber 101 by sliding the slider 141 in the slide groove 301.

[0031] It is worth noting that: an observation window 4 and a control panel 5 are installed on the outer surface of the grinding box 1. The grinding process can be observed through the observation window 4, and the switch of the grinding device can be controlled through the control panel 5. The grinding box 1 is divided into two rotatable parts through the mounting hole 102 and the rotating rod 17. A fixing ring 16 for fixing the two parts of the grinding box 1 is slidingly provided on the outer surface of the grinding box 1. When disassembly and cleaning is required, the sliding fixing ring 16 cancels the limit on the grinding box 1, and the grinding box 1 can be rotated and split through the mounting hole 102 and the rotating rod 17.

[0032] The further advantage of adopting the above method is that the malt after the initial grinding is filtered through the screening net 14 and then falls to the bottom of the grinding chamber 101, and the fine grinding component 3 is used to grind the malt for the second time. The arc-shaped bottom of the grinding chamber 101 is the same as the arc shape of the grinding rod 34 and is used in conjunction with it. During the grinding process, the malt can be prevented from being piled up at the four corners to form dead corners. The fine grinding of the malt ensures the uniformity of the malt grinding and improves the fermentation effect of the malt. The detachable installation of the fine grinding component 3 is completed through the connection group 32, and the screening net 14 is also a detachable structure through the slider 141 and the slide trough 301. After the grinding is completed, the fine grinding component 3 and the screening net 14 can be cleaned to avoid the retention of impurities such as dust and avoid the breeding of bacteria that affect the fermentation of malt powder.

[0033] The motor is of prior art, and its model is KYDAS96300-1 E, which can drive the grinding rod 34 and the grinding roller 22 to rotate respectively, and will not be described in detail here.

[0034] When the utility model is in use, the malt is firstly introduced into the grinding chamber 101 through the feeding port 12, and the grinding roller 22 is driven to rotate by the first motor 21. A baffle is movably arranged between the two filling blocks 15 to perform preliminary grinding on the malt, thereby improving the grinding efficiency and providing a basis for the later fine grinding, so that the grinding of the malt is finer. The malt after preliminary grinding passes through the screening net 14 and enters the bottom of the grinding chamber 101. At this time, the malt is finely ground under the action of the grinding rod 34 driven by the second motor 31. Since the curvature of the bottom of the grinding chamber 101 is the same as that of the grinding rod 34 and they are used in conjunction, the grinding rod 34 can evenly grind the malt in the grinding chamber 101, and the malt will not be scattered around, and the grinding dead corners are avoided, thereby achieving uniform grinding. After the grinding is completed, the detachable screening net 14 and the grinding rod 34 detached by the connecting group 32 can realize the cleaning of the device in the later stage, thereby avoiding the residual dust and other impurities due to incomplete cleaning, thereby causing bacteria to grow and affect the later fermentation.

[0035] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
