[0019] like Figures 1-13As shown, this utility model discloses a dry yogurt making device, which includes a support frame, a cylinder 4, a pressure plate 5, an outer cylinder 7, and a filter cylinder 8. The support frame includes a base plate 1, support screws 2, and a top plate 3. Multiple support screws 2 are provided, and their bottom ends are fixedly connected to the top surface of the base plate 1. The multiple support screws 2 are evenly distributed circumferentially around the center of the base plate 1. Multiple through holes II 303 are evenly distributed circumferentially on the top plate 3, and the number of through holes II 303 is the same as the number of support screws 2. Each support screw 2 passes through multiple through holes II 303. Nuts are connected to the support screw 2 above and below each through hole II 303. A top plate 3 is clamped between the nuts. A cylinder 4 is fixedly connected to the top surface of the top plate 3. The top plate 3 has a central hole 301, through which the piston rod of the cylinder 4 passes. A pressure plate 5 is fixedly connected to the end of the piston rod of the cylinder 4. A screw hole I 501 is provided on the top surface of the pressure plate 5, with a blind hole inside the screw hole I 501. The end of the piston rod of the cylinder 4 is provided with... There is a screw section 401, which is fixedly connected to the screw hole I 501. The side wall of the pressure plate 5 is provided with a screw hole II 502, which communicates with the screw hole I 501. A set screw 6 is connected in the screw hole II 502, and the front end of the set screw 6 abuts against the screw section 401. Multiple through holes II 303 are evenly distributed around the top surface of the top plate 3. The multiple through holes II 303 are all connected to the connection holes of the cylinder 4 through bolts. The outer cylinder 7 is fixedly connected between multiple support screws 2, along the high and low direction. The outer cylinder 7 is located between the base plate 1 and the top plate 3. The outer cylinder 7 includes a straight section 701. A bottom filter screen 706 is fixedly connected to the lower part of the straight section 701. A filter cylinder 8 is connected inside the outer cylinder 7 and is coaxial with the outer cylinder 7. The filter cylinder 8 includes a filter screen cylinder 801, which is connected to the top surface of the bottom filter screen 706. A pressure plate 5 is coaxial with the filter screen cylinder 801 and is slidably connected inside the filter screen cylinder 801. The outer diameter of the pressure plate 5 is slightly smaller than the inner diameter of the filter screen cylinder 801.

[0020] In use, the yogurt is placed in the cylindrical space formed by the filter cylinder 801 and the bottom filter 706. The cylinder 4 drives the pressure plate 5 to pressurize the yogurt. The whey liquid in the yogurt leaks out through the filter cylinder 801 and the bottom filter 706. Through the continuous pressurization of the yogurt by the pressure plate 5, dry yogurt is finally formed. The support frame mainly provides a support base for the cylinder 4 and the outer cylinder 7. The top plate 3 is positioned on the support screw 2 by the nut connected to the support screw 2, which facilitates the adjustment of different heights and leveling. In this embodiment, two nuts are connected to the support screw 2 above and below each through hole II 303. The two nuts interlock to prevent loosening.

[0021] It should be noted that when using this invention to make dry yogurt, the cylinder 4 drives the pressure plate 5 to press down, not to make the pressure plate 5 move continuously downward, but to position the pressure plate 5 after it has been pressed down to a suitable position, thereby forming continuous pressure on the yogurt. The suitable position of the pressure plate 5 can be determined according to different actual working conditions and through testing before production.

[0022] Since the pressure plate 5 continuously pressurizes the yogurt, it is necessary to consider that both the filter cylinder 801 and the bottom filter 706 will be subjected to pressure. Therefore, it is necessary to design the filter cylinder 801 and the bottom filter 706 to adapt to the pressure, so as to prevent the filter cylinder 801 and the bottom filter 706 from being damaged under continuous pressure on the yogurt.

[0023] The structure of the bottom filter screen 706 in this utility model is designed to adapt to pressure as follows: the outer cylinder 7 is provided with a support ring I 707, a support ring II 708 and a support rod I 709. The support ring I 707 is fixed on the outer wall of the bottom filter screen 706 and the outer wall of the support ring I 707 is fixedly connected to the inner wall of the straight cylinder section 701.

Multiple support rods I 709 are fixedly connected to the outer wall of the support ring II 708. The multiple support rods I 709 are evenly distributed circumferentially around the axis of the support ring II 708. The top surface of the multiple support rods I 709 away from the support ring II 708 is fixedly connected to the bottom surface of the support ring I 707.

[0024] The structural lightness of the bottom filter screen 706 is improved by setting support ring I 707, support ring II 708 and support rod I 709, without affecting the leakage of whey through the bottom filter screen 706.

[0025] The structure of the filter cylinder 801 designed to adapt to pressure in this utility model is as follows: the filter cylinder 8 includes a support ring III 802, a support ring IV 803, and support rods II 804. The support ring III 802 is fixedly connected to the bottom end of the filter cylinder 801, and the support ring IV 803 is fixedly connected to the top end of the filter cylinder 801. The filter cylinder 801, support ring III 802, and support ring IV 803 are coaxial. The support ring III 802 is connected to the top surface of the bottom filter screen 706. Multiple support rods II 804 are fixedly connected to the outer wall of the filter cylinder 801. The multiple support rods II 804 are evenly distributed circumferentially around the axis of the filter cylinder 801. The lower end of each support rod II 804 is fixedly connected to the outer wall of the support ring III 802, and the upper end of each support rod II 804 is fixedly connected to the outer wall of the support ring IV 803.

[0026] The structural lightness of the filter cylinder 801 is improved by setting support ring Ⅲ802, support ring Ⅳ803 and support rod Ⅱ804, without affecting the leakage of whey through the filter cylinder 801.

[0027] Considering the structural design for adapting the bottom filter 706 to pressure, and also the positioning issues of the installation into the straight section 701 and preventing the filter cylinder 801 from moving during pressurization of yogurt, the filter cylinder 8 of this utility model includes a positioning ring 805. The positioning ring 805 includes a straight pipe section 8051 and a positioning flange 8052. The positioning flange 8052 is fixedly connected to the top surface of the straight pipe section 8051, and the bottom surface of the straight pipe section 8051 is fixedly connected to the top surface of the support ring IV 803.

A support ring 705 is fixedly connected to the top of the inner wall of the straight section 701. The support ring 705 is coaxial with the straight section 701. The center of the support ring 705 is provided with a central hole II 7051. The filter cylinder 801 and the straight section 8051 both pass through the central hole II 7051. The positioning flange 8052 is connected to the top surface of the support ring 705. Multiple protrusions 8053 are evenly distributed around the outer wall of the positioning flange 8052. Multiple grooves 7052 are fixedly connected to the top surface of the support ring 705. The multiple grooves 7052 are all connected to the central hole II 7051. The number of multiple grooves 7052 is the same as the number of multiple protrusions 8053. The multiple protrusions 8053 are respectively connected to the multiple grooves 7052.

[0028] This invention provides support for the filter cylinder 8 by setting up a support ring 705 and a positioning ring 805, while also preventing the support ring 705 from exerting excessive pressure on the bottom filter screen 706 and damaging its structure. The invention also achieves positioning of the filter cylinder 8 by connecting multiple protrusions 8053 to multiple grooves 7052, and prevents the filter cylinder 8 from shifting when pressurizing yogurt.

[0030] This utility model uses the clamping cap 9 to clamp and position the filter cylinder 8, further preventing displacement when pressurizing the yogurt; the clamping cap 9 has a regular hexagonal cross-section, which makes it easy to rotate the clamping cap 9 with a wrench.

[0031] Once the yogurt is pressurized, raise the pressure plate 5, unscrew the clamping cap 9, and remove the filter cylinder 8 along with the compressed dry yogurt. Then, remove the dry yogurt from the filter cylinder 8.

[0032] Multiple support rods Ⅲ12 are fixedly connected to the outer wall of the straight section 701 of the outer cylinder. The multiple support rods Ⅲ12 are evenly distributed around the axis of the straight section 701.
