【発明の詳細な説明】
本発明は魚介類やその他の一般食品等を乾燥し
て乾燥品を製造するために使用される乾燥装置に
関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a drying apparatus used for drying seafood and other general foods to produce dried products.
従来から使用されているこの種の乾燥装置の中
には、熱風乾燥式と冷却乾燥式の２種類のものが
あるが、これらの乾燥装置には次のような問題点
があつた。 There are two types of drying devices of this kind that have been used in the past: a hot air drying type and a cooling drying type, but these drying devices have the following problems.
即ち、一方の熱風乾燥式の乾燥装置は、バーナ
等で加熱した空気を送風機によつて被乾燥物に吹
きつけ、その熱風によつて被乾燥物中の水分を蒸
発させて乾燥させるようにしているが、この熱風

介類の場合）が変性したりして品質が低下し、又
被乾燥物に吹きつけた熱風をそのまま大気中へ放
出させていたので熱損失が大きく、さらに乾燥時
に批乾燥物から発せられる臭気がそのまま外部へ
放出されるので悪臭公害を起こしていた。 That is, one hot air drying type drying device uses a blower to blow air heated by a burner or the like onto the material to be dried, and the hot air evaporates the moisture in the material to dry it. However, with this hot air drying method, the temperature of the hot air becomes too high, causing the dried material to lose its shape or protein (in the case of seafood) to denature, resulting in a decrease in quality. The hot air that was blown onto the dryer was directly released into the atmosphere, resulting in a large heat loss.Furthermore, the odor emitted from the dried material during drying was released directly to the outside, causing odor pollution.
又、他方の冷風乾燥式の乾燥装置は、例えばヒ

らに連続運転していると冷却器に着霜するためと
きどき冷凍装置の逆サイクル運転により冷却器の
除霜を行わなければならず運転効率が悪かつた。 On the other hand, the other cold air drying type drying device uses, for example, a heat pump type refrigerator cooler to blow dehumidified cold air around the object to be dried, and detects the difference between the degree of dryness of the surface of the object to be dried and the temperature of the cold air. This method accelerates the evaporation of water from the material to be dried. However, with this cold air drying method, the temperature of the cold air is low (usually below 22°C) and the drying time is long, which reduces the productivity of the drying process. In addition, only the surface of the material to be dried tends to dry out, causing what is called a "moist-dry" state.Furthermore, if the refrigerator is operated continuously, frost forms on the cooler, so it is sometimes necessary to defrost the cooler by operating the refrigeration equipment in reverse cycle. This resulted in poor operational efficiency.

特徴とするものである。 The present invention has been made with the aim of improving the problems of the conventional drying apparatus as described above. A blower and a dehumidifying cooler are installed in the drying chamber, and a condenser for defrosting the cooler is installed upstream of the cooler, and a condenser for indoor heating is installed downstream of the cooler. While air is circulated through the machine room, an outdoor heat dissipation condenser is further disposed outside the drying room, and the defrosting condenser, indoor heating condenser, and outdoor heat dissipation condenser are connected to the outlet of the compressor. A temperature sensor is connected in parallel between the side and the inlet side of the cooler, and is connected between the compressor and each of the indoor heating and outdoor heat radiation condensers to detect the temperature inside the drying chamber. a refrigerant control valve that is controlled to open and close in response to a signal from the drying chamber, and operates to control refrigerant supply to the indoor heating condenser and the outdoor heat dissipation condenser so that the temperature inside the drying chamber is maintained at a predetermined set temperature. is provided between the compressor and the defrosting condenser, and an opening/closing control unit is provided between the compressor and the defrosting condenser in response to a signal from a frosting sensor capable of detecting a frosting state or a frosting start condition in the cooler. A refrigerant control valve is provided which acts to control the supply of refrigerant to the defrosting condenser so as to prevent or defrost the condenser, thereby discharging the dehumidified air in the condenser. By heating the air to an appropriate temperature using an indoor heating condenser and circulating the heated dry air through the drying room and machine room, it is possible to produce high-quality dried products in a short time, and the thermal efficiency is good. This is characterized in that frost formation on the cooler is prevented or removed by the action of the condenser, allowing continuous operation without interrupting the dehumidifying action of the cooler.

and a humidity sensor 15b, which detects the temperature and humidity of the intake air W0 and inputs the signals to the calculation section 31 of the control panel 30. In this calculation unit 31, intake air W0 is calculated from these input signals to the cooler 4.
It is determined whether or not frost will form on the cooler 4 when the air is cooled by A signal is issued from the control unit 32 to open the refrigerant control valve 13 for the defrosting condenser 5 to supply high-temperature gas refrigerant to the defrosting condenser 5, thereby increasing the temperature of the suction air W 0 to frost. Raise it beyond the range of occurrence conditions. In addition, this frost sensor 15 is used not only as a sensor to prevent frost formation as described above, but also to detect the amount of frost formation on the cooler 4 and detect frost formation on the cooler 4 of a certain amount or more. If this occurs,
Suction air W 0 heated by the defrosting condenser 5

On the other hand, if it is necessary to liquefy the gas refrigerant by dissipating heat in the outdoor heat dissipation condenser 7, this is detected by, for example, a low-pressure gas refrigerant temperature sensor 17, and the refrigerant is controlled by a command from the control panel 30. The valve 12 is opened and high temperature gas refrigerant is supplied to the heat dissipation condenser 7.

徴とする乾燥装置。1 Air suction ports 2 each communicating with the inside of the drying chamber 1
A blower 8 and a dehumidifying cooler 4 are provided inside the machine room 2 having an air outlet 2 and an air outlet 23, and a condenser 5 for defrosting the cooler 4 is provided upstream of the cooler 4.
A condenser 6 for indoor heating is provided on the downstream side, and the air inside the drying chamber 1 is circulated through the machine room 2 by the blower 8, while a condenser 6 for outdoor heat radiation is provided outside the drying chamber 1. A condenser 7 is provided so that the defrosting condenser 5, indoor heating condenser 6, and outdoor heat dissipation condenser 7 are connected in parallel between the outlet side of the compressor 3 and the inlet side of the cooler 4. In addition, there is a connection between the compressor 3 and each of the condensers 6 and 7 for indoor heating and outdoor heat radiation, which opens and closes in response to a signal from a temperature sensor 16 that detects the temperature inside the drying chamber 1. Refrigerant control valves 11 and 12 act to control refrigerant supply to the indoor heating condenser 6 and the outdoor heat dissipation condenser 7 so that the temperature inside the drying chamber 1 is maintained at a predetermined set temperature. A frost sensor 1 is provided between the compressor 3 and the defrosting condenser 5 and is capable of detecting the frosting state or frosting start condition in the cooler 4.
The opening and closing of the cooler 4 is controlled in response to a signal from the cooler 4.
A drying device characterized in that it is provided with a refrigerant control valve 13 that acts to control the supply of refrigerant to the defrosting condenser 5 so as to prevent frost formation on or defrost the refrigerant.
