Description

  The present invention relates to a drying device for optimally drying sweet potatoes such as sweet potatoes, vegetables such as pumpkins and carrots, fruits such as grapes and persimmons, and furthermore, a tray for optimally drying squid and fish. And a drying chamber structure capable of storing a plurality of racks provided in parallel in a vertical direction.

  Today, many dried foods are manufactured and marketed by improving food processing technology. For example, dried sweet potatoes were originally made as a preserved food of sweet potatoes, but delicious dried sweet potatoes with an emphasis on taste and texture have been manufactured by improving drying techniques. In addition, dried pumpkins and dried carrots obtained by drying vegetables are widely used as ingredients for various dishes. Furthermore, dried fruits such as dried grapes and dried persimmons are widely recognized as foods that are good for beauty and health.

  For example, Patent Literature 1 discloses a method for producing a dried potato as a typical dried food. In this invention, first, the sweet potato is washed, and the washed sweet potato is sorted into large, medium, and small. Next, the selected potatoes are steamed, the skin is shaved, sliced into a plate shape, and the potatoes sliced to a predetermined width are dried and shipped as commodities.

  However, in the above method, the number of days for drying is, for example, about one week for sliced potatoes, and about one month for so-called roasting. During this period, if rain or high-temperature days continue, problems such as deterioration of the quality of dried potatoes or decay occur.

  For this reason, in order to shorten the drying period, a device in which potatoes are put into a dryer and dried by blowing air (dry air) heated by, for example, a boiler or the like has also been devised. However, in the conventional drying apparatus, the drying is simply performed by applying a drying air heated by a boiler or the like, which is an extremely inefficient operation. For example, there is a difference in the degree of dryness between a potato placed in a position where the drying air is directly applied and a potato placed around the potato, and it is not possible to perform a uniform drying operation of the dried potato. For this reason, for example, a complicated operation such as moving the position where the potatoes are placed in the dryer at regular intervals or adjusting the position of the drying air is required.

  This is not limited to the drying of dried potatoes, for example, the production of dried vegetables such as pumpkins and carrots, the production of dried fruits such as dried grapes and dried persimmons, as well as the production of dried squid and dried fish Met. Especially when the food to be dried is changed, more complicated work is required.

  Therefore, the present invention relates to a drying apparatus required for producing dried potatoes, dried vegetables, dried fruits, dried fish and the like, and in particular, by improving the structure of a drying chamber for accommodating each of the above-mentioned ingredients, the potato in the drying machine. Provided is a drying chamber structure capable of manufacturing dry foods with a uniform degree of dryness without the need for complicated operations such as movement of foods such as movement of foods and adjustment of the position of the dry air to the foods. Is what you do.

  According to the present invention, the above-mentioned object is to provide a plurality of trays on which foods to be dried are placed, a rack for vertically storing the trays in parallel, and a rack provided on both sides of the racks to be placed on the trays. And a side plate provided with a plurality of openings through which the drying air used for drying the food that is the target food to be dried is provided, and the structure of a drying chamber including a duct structure and a pressure fan, Dry air is passed through the narrow space divided by the upper and lower trays to dry the food that is the food to be dried, the indoor air is exhausted by switching the valve in the duct, and the outside air is sucked in. This can be achieved by providing a dry drying room structure.

  In addition, the drying air enters the space between the upper and lower trays formed in a cylindrical shape through the opening formed in the side plate, and contains air containing a large amount of moisture that has been subjected to the drying process of the food to be dried. In this configuration, the air is sent to the fan through an opening formed in the other side plate. The drying air introduced into the cylindrical food drying space from the opening of the side plate is air under optimal drying conditions sent through a circulation duct in the drying device.

  According to the present invention, for example, dried sweet potato, which is a target food for drying treatment, is stored in a cylindrical space partitioned by trays arranged in parallel one above the other, and the periphery of the space is closed. It is a cylindrical space, and the drying air input from the opening of one side plate is sent to the opening of the side plate arranged at the other end without leaking to the outside, efficiently drying the food such as dried potatoes. It can be carried out.
