  As an example of a food coating apparatus, there is an apparatus for coating an object with a liquid having a relatively high viscosity such as a sauce. Moreover, the food processing apparatus which processes an object for frying has a buttering apparatus and powder adhesion apparatuses, such as bread crumbs. A food processing apparatus for processing an object for tempura similarly has a battering apparatus. This battering apparatus also corresponds to an example of a food coating apparatus.

  There exists a thing shown in patent document 1 as such a coating apparatus for foodstuffs. The buttering apparatus of Patent Document 1 which is an example of a food coating apparatus includes a conveyor for conveying an object and a liquid spraying mechanism provided above the conveyor.

Japanese Utility Model Publication No. 54-63389

  A food coating apparatus represented by Patent Document 1 has the following problems.

  There is a problem that the object may have a portion where the liquid is to be attached and a portion where the liquid is not desired to be attached. For example, when the object is shrimp or fish is processed for frying with a battering device, the tail part of the shrimp or fish is the part where the batter is not desired to be attached.

  The food coating apparatus has a circulation mechanism that collects the sprayed liquid and sprays it again. There is a problem in that the temperature of the liquid changes greatly during circulation, the liquid deteriorates, or the physical property value of the liquid such as viscosity changes.

  If the impact of dropping onto the conveyor in the next process is large, there is a problem that the object is damaged or the coating becomes non-uniform. Moreover, since the viscosity of a liquid is high, there also exists a subject that the coated target object will bend | curve by the fall to the conveyor of a next process.

  There is a problem that the liquid adhering to the conveyor is squeezed by the downstream pulley and falls to the next process conveyor, and the next process conveyor becomes dirty. In a food processing apparatus that processes an object for frying, the next process of the coating process is a process of attaching bread crumbs to the object. In this case, there is a problem that the liquid falls on the bread crumbs on the conveyor of the next process and the bread crumbs deteriorate.

  When the conveyor is wound around the downstream pulley, there is a problem that the conveyor and the downstream pulley are difficult to separate due to the surface tension of the liquid attached to the conveyor.

  The food coating apparatus has a problem that the object rolls on the belt conveyor depending on the shape of the object.

  If the above problems are not solved, there is a problem that the product value is lowered or the production efficiency is lowered.

  In view of the above, an object of the present invention is to provide a food coating apparatus in which the stability of the quality of a processed object is improved and the production efficiency is improved.

  In order to solve the above-mentioned problems, a food coating apparatus according to claim 1 is provided above a belt conveyor that conveys an object and the object conveyed by the belt conveyor. The belt conveyor includes a multi-row belt arranged in a direction perpendicular to the conveying direction, an upstream pulley and a downstream pulley on which each multi-row belt is stretched. And is placed so that one end of the object extends from the other end in a direction perpendicular to the conveying direction, and a part of the pulley on the other end side of the placed object The radius is smaller than the radius of the other pulleys.

  In the food coating apparatus according to the first aspect, the conveying speed of the belts hung on some pulleys on the other end side is slower than the conveying speed of the belts hung on other pulleys. Therefore, one end of the object reaches the downstream end of the belt conveyor first and falls to the next process conveyor, and after a delay, the other end of the object reaches the downstream end of the belt conveyor and the next process conveyor. Fall into. The impact of the drop can be reduced by sequentially contacting the object from one end to the other end on the conveyor of the next process.

  In addition, in the process in which the coated object sequentially contacts the next process conveyor from one end to the other end, the coated object is placed on the belt conveyor of the next process while being stretched. Therefore, even if the viscosity of the liquid is high, it is possible to prevent the coated object from being bent by dropping onto the conveyor in the next process.

  The food coating apparatus according to claim 2 is the food coating apparatus according to claim 1, wherein a part of the food coating apparatus protrudes upward from between the multi-row belts and moves in the same direction as the conveying direction of the belt conveyor. Further, there is a conveyance assist means that abuts on the object placed on the belt, and the conveyance speed of the belt conveyor and the conveyance speed of the conveyance assist means are different.

The food coating apparatus according to the second aspect operates in the same manner as the food coating apparatus according to the first aspect, and the object is pressed against the protruding portion of the conveyance assisting means. Therefore, it can suppress that the target object of any shape rolls on the belt conveyor.

The food coating apparatus according to claim 1 or 2 improves the stability of the quality of the processed object and improves the production efficiency.

  Hereinafter, a food coating apparatus 1 according to an embodiment of the present invention will be described with reference to the drawings.

  As shown in FIG. 1, the food coating apparatus 1 includes a belt conveyor 2, a liquid flow-down means 3, a liquid storage means 4, a conveyance auxiliary means 5, and a fall delay means 6.

  The belt conveyor 2 conveys the object 10 with an endless annular belt 23. The liquid flow-down means 3 is provided above the belt conveyor 2. The liquid storage means 4 is provided below the belt conveyor 2. The conveyance assisting means 5 is provided inside the endless annular belt 23. The belt conveyor drop delay means 6 is provided in the vicinity of the downstream end of the belt conveyor 2.

  As shown in FIG. 1, the belt conveyor 2 includes an endless annular belt 23, an upstream pulley 21, and a downstream pulley 22. In FIG. 1, the direction indicated by the arrow A is the direction from the upstream side to the downstream side in the transport direction.

  As shown in FIG. 2, the endless annular belt 23 includes six multi-row belts 23a and three multi-row belts 23b. In the multi-row belt 23 a and the multi-row belt 23 b, the endless annular belt 23 is hung on the upstream pulley 21 on the upstream side, and the endless annular belt 23 is hung on the downstream pulley 22 on the downstream side. The multi-row belt 23a and the multi-row belt 23b are juxtaposed in a direction perpendicular to the conveying direction.

  As shown in FIGS. 2 and 3, the upstream pulley 21 is fixed with a cylinder 21 a and a cylinder 21 b having different radii on the rotation axis. As shown in FIG. 7, when the object 10 is placed, the upper side in FIG. 7 is one end of the object 10, and the lower side is the other end of the object 10.

  As shown in FIG.2 and FIG.7, the one part pulley of the other end side of the target object 10 is the cylinder 21b. The pulley of the other part of the target object 10 is a cylinder 21a.

  As shown in FIGS. 2 and 3, the six multi-row belts 23 a are hung on the side peripheral surface of the cylinder 21 a having a large radius. The three multi-row belts 23b are hung on the side peripheral surface of the cylinder 21b having a smaller radius. A plurality of grooves for guiding each multi-row belt 23a are formed on the side peripheral surface of the cylinder 21a at predetermined intervals in the axial direction. Grooves for guiding each multi-row belt 23b are formed on the side peripheral surface of the cylinder 21b.

  When the rotation shaft to which the cylinder 21a and the cylinder 21b are fixed rotates, the conveyance speed of the multiple-row belt 23b spanned on the cylinder 21b becomes slower than the conveyance speed of the multiple-row belt 23a spanned on the cylinder 21a. .

  As shown in FIG. 4, the downstream pulley 22 has a plurality of extending portions extending radially. At the tip of each extending portion, a recess into which the multi-row belt 23a or the multi-row belt 23b is fitted is formed. The downstream pulley 22 contacts the multi-row belt 23a or the multi-row belt 23b at the tips of the plurality of extending portions.

  As shown in FIG. 2, the same number of downstream pulleys 22 as the total of the multi-row belt 23a and the multi-row belt 23b are attached to the shaft at predetermined intervals in the axial direction. Each downstream pulley 22 is not fixed to the shaft, and can freely rotate with respect to the shaft.

  1 and 2, the upstream pulley 21 and the downstream pulley 22 are rotated in the direction of the arrow α by a drive motor (not shown). The rotation of the upstream pulley 21 and the downstream pulley 22 allows the multiple row belt 23a and the multiple row belt 23b to circulate between the upstream side and the downstream side in the transport direction.

  A multi-row belt 23 a and a multi-row belt 23 b are arranged in parallel from the upstream pulley 21 toward the downstream pulley 22.

  As shown in FIG. 1, the liquid flowing-down means 3 causes the liquid 30 to flow down toward the object conveyed by the belt conveyor 2. The liquid flow down means 3 has a chute plate 31 that guides the position where the liquid 30 flows down. The chute plates 31 are provided at four locations with an interval in the transport direction.

  Each chute plate 31 is movable in the width direction of the belt conveyor 2 as shown by a double arrow B in FIG. By moving the chute plate 31, the range of the object to be coated with the liquid 30 can be adjusted.

  As shown in FIG. 1, a liquid supply pipe 47 is connected to the liquid flow-down means 3 and the liquid storage means 4. The liquid 30 is supplied from the liquid storage means 4 to the liquid flow-down means 3 through the liquid supply pipe 47.

  In FIG. 1 and FIG. 2, the configuration is partially omitted, but the liquid 30 stored in the liquid storage unit 4 is supplied to the liquid flow-down unit 3, and the liquid 30 flowed down by the liquid flow-down unit 3 is recovered. The liquid 30 can be circulated by storing the recovered liquid 30 in the liquid storage means 4 and supplying the liquid 30 to the liquid flow-down means 3 again.

  As shown in FIG. 6, the liquid storage means 4 has an outer box 42 and an inner box 41.

  The inner box 41 is fixed inside the outer box 42 by an inner box fixing member 43.

  The outer box 42 can store fluid. The fluid can circulate the fluid stored in the outer box 42 by the pump 48, the fluid supply pipe 45, and the fluid discharge pipe 46. The fluid temperature change can be suppressed by the circulation of the fluid and the cooling or heating of the fluid.

  The inner box 41 can store the coating liquid 30. The inner box 41 is a space for storing the liquid 30 of the liquid storage means. A cylindrical body 44 passes through the inner box 41. Both ends of the cylindrical body 44 are open to the internal space of the outer box 42. Therefore, the fluid stored in the outer box 42 can pass through the cylindrical body 44.

  Since the temperature change of the fluid stored in the outer box 42 is suppressed, the fluid passes through the cylindrical body 44 and the temperature change of the coating liquid 30 stored in the inner box 41 can be suppressed.

  As shown in FIGS. 1, 2, and 7, the conveyance assisting unit 5 includes upstream gears 54 a and 54 b, downstream gears 55 a and 55 b, chains 51 a and 51 b, a bridge portion 52, and a claw portion 53. Have

  The upstream gears 54 a and 54 b are a pair of gears that face each other in the width direction of the belt conveyor 2. The downstream gears 55a and 55b are also a pair of gears facing the width direction of the belt conveyor 2.

  The chain 51a is hung on the upstream gear 54a and the downstream gear 55a arranged in the transport direction. The chain 51b is hung on the upstream gear 54b and the downstream gear 55b arranged in the transport direction. The two chains 51a and 51b are parallel to the transport direction.

  Between the two parallel chains 51a and 51b, a plurality of bridge portions 52 are provided at a predetermined interval.

  As shown in FIGS. 2 and 7, a plurality of claw portions 53 are formed so as to extend upward from the respective spanning portions 52. The claw portion 53 protrudes upward from between the multiple row belts 23a and 23b.

  The upstream gears 54a and 54b and the downstream gears 55a and 55b rotate in the direction of arrow β in FIG. The claw portion 53 moves in the same direction as the conveying direction of the belt conveyor 2.

  The speed of the multi-row belt 23 in the transport direction is slower than the speed of the claw portion 53 in the transport direction. Accordingly, in a section in which the claw portion 53 protrudes upward from between the multiple row belts 23a and 23b and moves in the same direction as the multiple row belts 23a and 23b, the claw portion 53 is placed on the multiple row belt 23a and the multiple row belt 23b. The placed object 10 is pressed against the claw portion 53.

  When the food coating apparatus 1 is a fattering apparatus for frying, for example, the object 10 is shrimp and the liquid 30 is a batter. The chute plates 31 for letting the batter flow down are provided at four locations at intervals in the transport direction.

  If the shrimp passes below the chute plate 31 on the most upstream side and the shrimp is coated with a batter, the shrimp may be bent due to the high viscosity of the batter.

  However, when the shrimp as the object 10 is pressed against the claw portion 53, the shrimp can be prevented from bending even when passing under the chute plate 31 on the downstream side. Thereby, a batter can be uniformly coated on the surface of shrimp.

  The fall delay means 6 is provided in the vicinity of the downstream end of the belt conveyor 2. The fall delay means 6 includes a support member 61 and a swing member 62.

  The other end of the object 10 conveyed while being placed on the belt conveyor 2 comes into contact with the swing member 62. Due to the contact between the other end of the object 10 and the swing member 62, the fall of the other end side of the object 10 is delayed from the fall of the one end side of the object 10 at the downstream end of the belt conveyor. .
