Description

Cold press milking machine {COLD OIL PRESS}

The present invention relates to a cold press milking machine, and more particularly, the grain supplied through the input hopper is heated at low temperature through a band heater cylinder arranged to be wrapped around the outer periphery of the transfer screw while moving along the spiral direction of the transfer screw. , The oil produced while being cooled and compressed through the compression cylinder through the cooling cylinder disposed on the outer periphery of the end of the transfer screw is moved to the rear, and the compressed grain residues are moved to the front and discharged. At this time, the milking cylinder disposed in front of the cooling cylinder It relates to a cold press milking machine with improved performance so that the oil can be discharged smoothly through the

The conventional milking machine is to obtain oil by squeezing various grains such as sesame, perilla, peanut, plant seeds, fruits, etc., and milks the oil by applying heat or pressure.

Accordingly, it is composed of a screw for moving grains and a cylinder covering and covering the outer circumferential surface of the screw, and the grains fed into one inlet of the cylinder are compressed while forcibly transported through the milking unit along the screw inside to milk the oil.

And, in the conventional milking machine, while moving grain through the screw, the grain is squeezed through the interference between the pressure tube located at the end of the screw and the inclined outer circumferential surface of the screw, and the oil is discharged through a process of generating oil. The high heat generated in the process heats the grain, causing the oil to leak out.

However, the milking efficiency from grains is reduced due to the instantaneous high heat generated during the pressing process of grains, which is transmitted only to the surface of the grains without being able to transmit the high heat generated during the pressing process to the whole grain. It has a problem in that the production of oil from the grain is reduced.

The curved groove 312 is installed on the connecting rod 310 formed, and the connecting rod 310 is divided into two equal parts along the longitudinal direction, so that the first body 310a on one side and the second body 310b on the other side are equally divided. is divided into, the upper width of the coupling gap 314 while the coupling gap 314 is formed between the first body 310a and the second body 310b to have a larger width than the lower width of the first, 2 The surfaces facing each other of the bodies 310a and 310b form a symmetrical stepped surface 315,
It is provided between the first body 310a and the second body 310b, and the center is connected to the upper end of the vertical plate type support plate 321 inserted into the coupling gap 314 and the support plate 321 and is coupled. The blocking tab 322 bound to the receiving groove 316 of the outer peripheral surface of the first and second bodies 310a and 310b in which the upper end of the gap 314 is located and the lower end of the support plate 321 are connected to the curved groove 312 Cold press milking machine, characterized in that it further comprises a discharge diffuser 320 consisting of a diffusion portion 323 formed in a mutually symmetrical form with inclined plates 323-1 on both sides, respectively. The method of claim 1,
It is coupled to the side of the discharge cylinder (600). One end of the coupling part 710 is formed symmetrically on both sides of the disc-shaped coupling part 710 in which the through hole 711 passing through the transfer screw 100 is formed in the center, and the coupling part 710 is the outer periphery of the coupling part 710 . A first connecting plate 720 connected to a single surface, and one end connected to the other end of the first connecting plate 720 is bent inside the coupling portion 710, and the blade portion 731 cut diagonally at the other end is Cold press milking machine, characterized in that it further comprises a discharge cutting socket 700 made of a second connecting plate 730 formed close to the outer peripheral surface of the blade portion (731) end of the transfer screw (100) as it is formed. The method of claim 1,
A plurality of spiral grooves are formed on the inner peripheral surface of each of the first band heater cylinder 200a, the second band heater cylinder 200b and the cooling cylinder 400, or have a structure in which a plurality of cylindrical teeth are arranged on the inner peripheral surface. Features a cold press milking machine.
