Using plastic bags as a container, closed-type production, each half kilogram of green beans can produce 6 kilograms of white stout quality bean sprouts. The production of the shoot-growing cans: Select a corner of the room and build a single-brick empty trough of 4.5 meters in length and 0.8 meters in height at a distance of 99 cm from the wall. From the bottom up, leave holes in the 57th row of bricks at the 4th row, leaving 3 holes every 82 cm. Take 5 pieces of 2.8 meters of linoleum and fold them outwards at a width of 80 cm. Then circle the circle and lap 12 cm into a cylinder and put it in a good groove. The distance between the barrel and the barrel, the barrel and the wall is 7 cm. Then fill the straw with wheat straw or firewood and compact it. The inside of the cylinder is half-foot thick, and the area near the brick hole is slightly thinner to form a slope drainage. Cut a linoleum round gasket with a diameter of 85 cm and put it in a lining cylinder so that the inside is clean and does not show firewood and other insulation. Cut a 3.5-meter-long, 1.5-meter-wide cylindrical plastic film into 5 pieces of 90 cm long. Grab the side of each piece, and cut a hole in the corner of the pinch. Insert 33 cm in length and 1.65 cm in inside diameter. Hard plastic tube and tied with a string. One end of the plastic tube inserted into the bag must be pre-coiled with two holes of coarse wire and wrapped with a window screen to prevent the green beans from bursting out. Put the plastic bag into the felt cylinder and position it at the bottom of the cylinder in front of the cylinder. Align with the narrow wall cutting hole. The pipe of the plastic bag protrudes out of the wall through this hole. Flatten the plastic bag around it. The outside of the tank should be turned outwards and set on the top edge of the cylinder. Plastic Bag Underlay A plastic film round gasket with a diameter of 85 cm, covering uneven wrinkles, to prevent rotting beans due to water retention.
