  An object of the present invention is to form a layer of ingredients having a thickness suitable for drying by a drying device, using an ingredient conveying step.

  The present invention relates to a plurality of conveyors having different installation heights and transport speeds, and one or a plurality of rectifying members that disperse the ingredients in the width direction of the conveyor and limit the layers of the ingredients to a certain height or less. Are combined to form a layer of ingredients suitable for a drying apparatus.

  ADVANTAGE OF THE INVENTION According to this invention, productivity of the material drying process by a drying apparatus can be improved, without producing damage and drying unevenness to a material.

FIG. 1 is a plan view of a conveying device and a drying device for conveying ingredients. FIG. 2 is a cross-sectional view of a conveying device and a drying device for conveying ingredients. FIG. 3 is a perspective view of a transport device for transporting ingredients. FIG. 4 is a plan view of a rectifying member constituted by a plurality of linear outer walls.

  Embodiments of the present invention will be described below. Note that the present invention is not limited to the following embodiments. FIG. 1 is a plan view of a transport device and a drying device for transporting ingredients according to the present invention, FIG. 2 is a cross-sectional view of the transport device and the drying device for transporting ingredients, and FIG. It is a perspective view of the conveying apparatus which conveys.

  1 to 3, examples of the ingredients 8 that are conveyed by the conveying device 1 and dried by hot air by the drying device 7 include, for example, a mixture of egg yolk powder, starch, and an expanding agent to prepare a powder mixture, It is possible to use particulate ingredients that have been added to the body mixture with water or seasoning to form a small lump, steamed, and cooled, but any ingredients that can be dried with hot air using a drying device can be used. It doesn't matter.

  The conveying device 1 according to the present invention is installed at a position lower than the first conveyor 2 into which the ingredients 8 are introduced from an insertion port (not shown) and the first conveyor 2, and falls from the end of the first conveyor 2. The second conveyor 3 that receives the material 8 and conveys it downstream, and the material 8 that is provided on the second conveyor 3 and is distributed in the width direction of the conveyor, and the second conveyor 3 The first rectifying member 5 that restricts the layer of ingredients passing through the gap between the first height and the second height is lower than the second conveyor 3, and the end of the second conveyor 3 It comprises a third conveyor 4 that receives the falling ingredients 8 and conveys them downstream. In addition, on the third conveyor 4, the ingredients 8 conveyed by the third conveyor 4 are dispersed in the width direction of the conveyor, and a layer of ingredients passing through the gap between the third conveyor 4 is provided. There is further provided a second rectifying member 6 that is limited to the second height or less.

  As shown in FIG. 3, the first rectifying member 5 and the second rectifying member 6 have a V-shaped outer wall having a predetermined height, so that the ingredients 8 conveyed by each conveyor are Dispersed in the width direction of the conveyor by the V-shaped outer wall. In addition, since a gap is provided between each rectifying member and each conveyor, the ingredient 8 below the outer wall passes through each gap and is conveyed downstream. When the left and right outer walls constituting the V-shaped outer wall are arranged symmetrically with respect to the central axis of the conveyor, the angle formed by the left and right outer walls can be set in a range of 45 ° to 180 °. , 90 ° to 110 ° is preferable. Moreover, as shown in FIG. 4, each of the 1st rectification member 5 and the 2nd rectification member 6 can also be comprised with the some linear outer wall parallel to mutually.

  Since the drying device 7 is provided downstream of the transport device 1, the hot air can be dried for a predetermined time while the material 8 is transported by the third conveyor 4 of the transport device 1.

Here, the conveyance process of the ingredient 8 is shown below. The charged material 8 is transported downstream at the transport speed V ₁ by the first conveyor 2, and is orthogonal to the transport direction of the first conveyor 2 from the end of the first conveyor 2 and the first To the second conveyor 3 installed at a position lower than the conveyor 2. Ingredients 8 which are introduced into the second conveyor 3 is further conveyed downstream at the conveying speed V _2. Since the first rectifying member 5 having a V-shaped outer wall as viewed from the upstream is provided on the second conveyor 3, the ingredients 8 are dispersed in the width direction of the second conveyor 3 by the outer wall. The Further, the thickness of the layer of the material 8 passing through the gap between the first rectifying member 5 and the second conveyor 3 is limited to the _first height h ₁ or less as shown in FIG. It will be.

The conveyance speed V2 of the _second conveyor 3 is set to be smaller than the conveyance speed V1 of the _first conveyor 2, and the first rectifying member 5 has a V-shaped outer wall. The material 8 can be dispersed in the width direction of the second conveyor 3 by the V-shaped outer wall while increasing the thickness of the layer of the material 8 due to the speed difference.

Subsequently, the ingredients 8 are placed from the end of the second conveyor 3 to the third conveyor 4 that is installed at a lower position than the second conveyor 3 and has a wider lateral width. The third conveyor 4 ingredients 8 which are turned on is further conveyed downstream at the conveying speed V _3. Since the second rectifying member 6 having a V-shaped outer wall as viewed from the upstream is provided on the third conveyor 4, the material 8 is dispersed in the width direction of the third conveyor 4 by the outer wall. Is done. Further, the thickness of the layer of the material 8 passing through the gap between the second rectifying member 6 and the third conveyor 4 is set to be equal to or less than the second height h ₂ as shown in FIG. Will be limited.

The conveyance speed V ₃ of the third conveyor 4 is set to be smaller than the conveyance speed V ₂ of the second conveyor 3, and the second rectifying member 6 has a V-shape, and therefore the conveyance speed speed. The material 8 can be dispersed in the width direction of the third conveyor 4 by the V-shaped outer wall while further increasing the thickness of the layer of the material 8 due to the difference.

  In this way, by combining a plurality of conveyors whose transport speed becomes slower as going downstream, and one or a plurality of rectifying members provided on the conveyor, in the width direction of the conveyor without damaging the ingredients. It is possible to disperse and laminate the ingredients sequentially to form an ingredient layer having a thickness suitable for drying with a drying device.

The conveying speed of each conveyor is determined by the length of the conveying path in the cabinet of the drying apparatus, the drying time, and the drying temperature. The length of the conveying path of the drying apparatus is 5 to 6 meters, the drying time is 10 minutes, and the drying temperature When the temperature is 35 ° C. to 65 ° C., the first transport speed V ₁ is 6 meters / minute to 8 meters / minute, and the second transport speed V ₂ is 1.5 meters / minute to 2.5 meters / minute. , third velocity _{V 3} is preferably set to 0.5 meters to 0.6 meters / minute.

The second height h ₂ of the second rectifying element 6 is uneven drying by the drying apparatus is determined by the thickness of the ingredients does not occur, for example, be a value within the range of 20mm~85mm Is preferred. Furthermore, the first height h ₁ of the first rectifying member 5 is set to a value smaller than the second height h ₂ of the second rectifying member 6, for example, a value in the range of 5 mm to 35 mm. It is preferable to set. The first height h ₁ and the second height h ₂ may be changed manually or automatically.
