Abstract

Shrimp graders are suitable for the food manufacturing industry, especially frozen shrimp for export, where Thailand is a major source of shrimp exports. Which machine The size of this shrimp is simple to operate using a belt device, a motor and a drive roller to Receive and deliver according to the size of the shrimp. The shrimp sizing machines are cheaper than those of foreign countries but can be sorted quickly and standardized. And prawns have little damage Make it an added value And product quality Along with facilitating operators to be able to work At a glance

Claims (8)

This shrimp sorter (1) has a pump (2) installed for circulation. Then in the shrimp tank (1) to clean the body. Shrimp by the water that will pass into the pump (2) will pass through a water filter (3) to remove impurities and can enter Ice to adjust shrimp temperature The shrimp receiving tank (1) can be moved. The belt unit (6) has a step-like fin. The belt unit (6) will be installed in an upward motion to transport the shrimp. Up before going into the sorting process In which the belt unit (6) is driven by a gear motor (7) that can adjust the speed by transmitting power through the chain (8) to drive the shaft of the belt unit (6) to the belt unit (6) to work with the set. The belt (6) can be tilted up and down for cleaning and maintenance purposes. The cover (9) is a long, inverted half circle that is installed at the beginning of the sorter (12) and at the beginning of The sizing unit is equipped with a water spray system (10) with an upside-down U-shaped hollow tube (U), with a channel (11) that allows clean water to be ejected. At least one (13) long pair works by rotating in reverse. And long roller 13 will tilt at an angle of 10-15 degrees when measured from the horizontal level The characteristics of the rollers (13) will be smaller in stages where the diameter and length of the rollers will initially be reduced periodically according to the suitability of the shrimps to be screened. Where the first period is the width of The diameter and length of the long roller (13) are larger and longer, and the diameter of the diameter. Middle and length are reduced accordingly. And at the body of the long roller (13) is a groove (14) deep in the body of the long roller (13). There will be a gear motor (16) to transmit power by the belt. To drive the chain sprocket (17) then the chain sprocket (17) will drive the long roller sprocket (18) to rotate by means of the chain as a power relay and at the end of the sizing unit (12) there is a tensioning gear. (19) which is stronger than a long roller gear (18) to support the forces arising from this drive unit. The remaining sprocket is for guiding the chain to prevent slack - Ratchet (20,21), which is installed at the top and bottom of the sorter (12) on both sides. Of the sides on the top sizing head (22) and the lower sizing head (23) respectively for adjustment The distance of the long roller pairs (13) to the appropriate distance to the size of the shrimp to be screened - each size of shrimp support tray after passing through the shrimp screening process and moving along the pan set (24) to Send the shrimp out of the grader. 2. Shrimp Sorter According to claim No. 1, which still has a water tank (5), a cold water tank To reserve in case There is no cold water in the system. 3. Shrimp Sorter According to claim 1, where at the bottom of the belt unit (6) there is a cover plate with The hemispherical shape covers the arc of the belt unit (6) to prevent the shrimp from reflux. Return to the shrimp tank (1). 4. Shrimp Sorter According to claim 1, the groove (14) will have an unbuttoned part, leaving a 5-10 cm gap of each span on the long roller (13) in order to maintain the structure of the long roller (13) to be strong. 5. Shrimp Sorter According to claim 1 or 4, the width of the groove (14) is 25-35 mm, depending on the size of the long roller (13). 6. Shrimp Sorter According to claim 1, between the upper ratchet 20 and the lower ratchet (21), a compression screw is applied to the longitudinal roller stand (13) both above and below. This is to prevent the long roller spacing (13) from changing during vibration caused by the operation of the shrimp sorter. 7. Shrimp Sorter According to claim 1 or 6, at the top of the longitudinal roller (13) there is a frame (15) over it to protect people from entering the sizing unit (12). 8. Shrimp Sorter According to any of the claims 1 to 7 Which may have a set of belts for shrimp delivery Enter two consecutive sets of size selection set, belt unit (25) and belt unit (26), to wash the shrimp once. Second, and distribute the shrimps that were fed into the screening unit (12) so that they are even and not clumping.
