3. reasonable vibration direction and optimized outlet duct can ensure that material will not flow out of the stone outlet when the machine is turned on or off. 4. engine-driven arc welding process is used to weld the studs and nuts at joints of certain parts in order to ensure perfect appearance based on maintaining structural strength. 5.
destoner application the machine is used for removal of heavy foreign contaminants like stones, metallic and glass pieces, etc. from grains and seeds of all crops. it works on the principle of weight/gravity separations with stratification by positive pressure fan salient features all steel welded construction. compact & rugged design.
1.introduction of the new design small grain cleaner soybean seed cleaning machine cleaning with destone machine for beans plum stone remover: this destoner machine is used for the food process business enterprise,separate the stone,pebble,clod from wheat,paddy rice,corn,seasame etc,according to the material weigth and size difference to

the air-screen machine is the basic cleaner in most seed processing plants. almost all seed must be cleaned by air-screen cleaner before specific specifications can be attempted. machine size varies from small, two-screen farm models to large industrial cleaners with 7-8 screens.
when gravity destoner work, the material from the hopper to continue into the middle of the screen surface of the stone due to vibration and air flow through the material layer of the role screen surface, so that the porosity between the particles increases, the material in a fluidized state promote the automatic classification, heavy stones and sank the bottom of the screen surface in contact, a small proportion
specification. vqsx series gravity destoner is mainly used to separate the heavy impurities such as stone, mud and so on from wheat, white rice and paddy. it has features as no spreading power and dust, fine firmness and durability, easy classifying & maintenance, its
working principle. the product, flows through the superior part of the machine and with the effect of the vibration and a particular distribution system, spread on superior frame divided in three parts with different sizes and perforations.
the machines currently used for processing of small millets on a small to medium scale include, i) graders / shakers, ii) destoners, iii) air classifier / aspirator andiv) hullers. currently three types of dehulling technologies are employed namely, 1. emery mill working on abrasion principle, 2.rubber
the segregation patterns on the deck of a destoner are principally controlled by two main variables: fluidizing air and deck tilt. the dependence of the performance of the machine on just these two parameters enables tighter control on quality and relative ease of operation. the lack of prior work
the working principle of gravity destoner wuhan anon . pdf design construction and performance evaluation of the working principle of gravity destoner posted at am, september 2016 category: industry news gravity destoner is based on the proportion of different food grain and gravel and suspension speed, the grain size and grain shape approximate grain sand and other debris separated from the
working principle: in magnetic destoner separator, a short conveyor belt envelopes the magnetic roll and a tensioning ideal roll. a suitable feeder discharges materials on the belt. the ferromagnetic and paramagnetic particles adhere to the belt while the nonmagnetic particles flow
color sorters are the machines that are used in the food processing line to separate grains by their colors. color sorter separate items by their colors and pneumatic ejection devices are placed in processing line to divert items whose colors do no fall within the acceptable range. role of magnetic destoner:
application of aerodynamic force. another machine for the separation of dust and stone from rice is the stoner separator (chackravery, 1981). multi crop cleaner has been developed by ademosun (1993). ozormba described rice destoner as a machine, which takes advantage of the difference in axial velocities of rice and stone.
(1)main equipment and working principle of milling flour milling mainly equipment is flour mill, high square plansifter, flour cleaning machine flour milling machine:consisting of a pair of grinding rollers with a diameter of 250mm 1000mm, two roller speed is different, one is called slow roll, one is called fast roller, wheat or intermediate particles fall into between two rollers, with a
one such grain cleaning operation is the ‘density-based separation’ using a destoner. this process removes stones and other heavy material from lighter food grains using a vibrating deck and
rice destoner is a machine that separates the side-by-side grains in the grain (grain shape similar to grain size) from the ground. it has the advantages of good stone removal effect, simple structure, small volume and low energy consumption. after rice was cleaned by rice destoner, the stone removal rate was greater than 95%.
destoner negative pressure type used for removal of heavy foreign contaminants like stone, metallic pieces, glass pieces, mud balls etc. it works on the principle of vaccum negative pressure. features all steel welded construction rectangular vibrating deck the machine is pre-wired from electric motor to connection for in coming power supply.
the destoner operates on the basic principle of flowing dry granular material over a vibrating, screen covered deck that is inclined. forsberg manufactures two types of destoners: pressure-type with an open deck and the fan placed inside the box creating a positive air
machine is loaded through the hopper, which is regulated at the base by a slider unto the sieve assembly via the grain distributor. then air from the blower is directed over the falling rice grains and materials other than grains (mog) larger, light impurities, chaffs, and dust are blown out of the machine. figure 1.
