[Previous technology] For example, the tea industry and Chinese medicinal materials need to be edible through drying technology. In order to preserve agricultural products for a long time and provide different tasting flavors for the public, different vegetables and fruits are also dried and stored, such as shiitake mushrooms. , Green beans, jackfruit, apples, sweet potatoes, fish, meat, etc. Therefore, the application range of air-drying technology is getting wider and larger, and the earlier air-drying technology used high-temperature air or high-temperature radiation to continuously blow dry food However, since food is continuously subjected to high-temperature air blowing or radiation, the food will often be shortened and the surface will be incomplete, and even the original nutrition and proper flavor will be destroyed. Therefore, the applicant of this creation has proposed a low temperature The freeze-dryer in the drying method to preserve food nutrients is a new patent case (hereinafter referred to as the reference case) of the patent No. 1841 "Freeze-dryer". Its main technology is to send low-temperature dry air into the In the storage box, the water and gas to be dried are taken away by the tortuous partition in the storage box to form humid air. The air fed into the dehumidifying space, and the outlet of the cold air of the dehumidifying space while the cold feed, whereby cold moist air to condense. In short, the reference case is blowing out low-temperature dry air, and inhaling moist air with moisture and slightly warming. This method of drying food by dry cold air can indeed prevent the food from shortening and maintain the original flavor. And nutrition. However, it was found that the dryness of the food 5 M240086 on the upper and lower levels of the storage box will be different, because of the reason: Because the partitions in the storage box of the reference case are staggered, that is, the air of Circulation is blowing from top to bottom, but because the air blows through the food, the water vapor of the food will be taken away at the same time, so when the air blows to the lower layer, the air already has water vapor, so that in the same time, The food on the upper layer has the best dryness, and the food on the lower layer has the worst dryness. If the food on the upper layer is taken as the standard, the lower layer does not meet the drying standard. On the contrary, if the lower layer When the food on the partition is a dry standard, the food on the upper layer is too dry, making it extremely difficult to handle. φ Therefore, although the aforementioned reference can improve the conventional method for drying fresh foods with high-heat air, there is still a case where the food is not uniformly dried, and it is necessary to improve it. [New content] In order to improve the above-mentioned shortcomings, the main purpose of this creation is to provide a food freeze dryer that can make foods be uniformly blown by dry and warm air to achieve the same degree of drying. Based on the above purpose, the main technical means of this creation is to provide a 4 food freeze dryer, which is connected to a hollow casing with a refrigerating and air-conditioning system in the second half, and the first half of the interior space of the cabinet is at least separated by a screen. A storage space is enclosed, and several horizontal storage trays are arranged inside the storage space. An air inlet duct and a return air duct are respectively formed on the outer side of the storage space, and are located on the top surface of the screen and the top surface of the casing. There is a condenser adjacent to the return air duct, and a heating row and an electric heating pipe are provided on the side of the condenser facing the side plate of the cabinet, and a fan unit adjacent to the air inlet duct is provided between the electric heating pipe and the side plate. The 6 M240086 air supply port of the fan unit is connected to the air intake duct. With the above-mentioned technical means, during the air-drying operation, the fan unit draws in the dry and warm air and blows it into the air duct through the air outlet, and blows into the accommodation space through the mesh holes on the screen to blow the air on the tray. The objects to be dried are taken away, and the water and gas on the objects to be dried are taken away. Since the dry air is used to enter the air inlet duct during the drying operation, it then passes through the screen and then enters the accommodation space. The material to be dried is simultaneously blown by dry and warm air, and its drying degree is the same, which improves its uniform quality. [Embodiment] Please refer to the first, second and third figures. The food freeze dryer provided by this creation has a hollow casing (1 0), and the inner half of the casing (10) is installed. There are compressor units (A), radiators (B), expansion valves (not shown), and other refrigeration and air-conditioning systems. Since this system is known, it will not be described, and the internal space of the casing (1 0) In the first half, at least a screen plate (11) is used to surround an accommodating space (12), and two inner side walls of the accommodating space (1 2) are opposite to each other and are provided with disc racks (1 1 1) for installation. The storage tray (2 1) to be dried is placed on the tray rack (1 1 1). In the preferred embodiment, two rows of storage spaces (1 2) are provided at intervals, and the two storage spaces (1 2) An air inlet duct (1 3) is formed between the side plate (100) of the casing (10), and an air return duct (1 4) is provided between the two accommodation spaces (1 2). ), There are several germicidal lamps (30) in the return air duct (1 4), and there are filter screens (1 5) on both sides of the return air duct (1 4), and they are located on the top of the screen (1 1) Back to the top surface of the casing (1 0) The air duct (1 4) is provided with a condenser (40) M240086 'and the condenser (4 〇) is facing the casing (1 〇) side plate (100). The side is provided with a heating bar (4 Ο 1) And electric heating pipe (50), and between the electric heating pipe (50) and the side plate (100), there is a fan group (60) adjacent to the air inlet duct (13), and the air supply of the fan group (60) The opening (6 1) is in communication with the inlet duct (1 3), and an inclined guide plate (7 0) is arranged at the top of the inlet duct (1 3), and the guide system of the guide plate (7 0) is arranged. Towards the side of the screen (1 1). The above is a description of the configuration of the components of this creation. When performing air-drying operations, it is to start the refrigeration air-conditioning system on the rear side and the condenser (40), heating bar (401), electric heating tube (50), and fan unit located on the upper side. (60), etc., the fan unit (60) draws in air and then blows it into the air duct (13) through the air outlet (61), and is guided by the air guide plate (70), and the screen plate (1 1) The above meshes are blown into the accommodating space (1 2), use the object to be dried on the tray (2 1), and take away the water and gas on the object to be dried. At this time, the dry air It will be turned into humid air and may contain bacteria and impurities and enter the return air duct (1 4). The coarse particles are filtered by the filter (1 5) and sterilized by the germicidal lamp (30). The clean wet air that has been sterilized and filtered by impurities is sucked by the fan unit (60) and passes through the condenser (40) to condense the water vapor into water droplets. At this time, the condensed dry air is condensed due to the condensation. The temperature is reduced due to factors, so it is heated back by the heating bar (4 0 1) and the electric heating tube (50). The warm and dry air is sucked into the fan unit (60) and then enters the air duct (13) to continue to dry the dried material. After a period of time, the water of the dried material will be completely taken away and M240086 retains the original flavor and ingredients. The above-mentioned preferred embodiment is built into the storage tray (2 1) directly in the storage space (1 2). When the food freeze dryer is used for air-drying operation, the operator can also use the dryer in the dryer as shown in the fourth figure. The next batch of objects to be dried is placed on an outer trolley (20) in advance. After the air-drying operation is completed, the food freeze dryer can be opened, and the tray (2 1) in the cabinet (10) can be taken out and placed. On the outer trolley (20), the tray (2 1) on the outer trolley (20) which has been prepared in advance to be dried is put into the accommodating space (1 2) to save operation time. In addition, it can also place the storage tray (2 1) on the trolley (80) as shown in the fifth figure. After the drying operation is completed, take out the entire trolley (80) and then place another The trolley with the objects to be dried can be pushed into the freeze dryer. As can be seen from the above, the design of this creation has several advantages: 1 · Because this work uses warm dry air to enter the air duct (1 3) during the drying operation, it then passes through the screen (1 1) on average. Then it enters the storage space (1 2). Therefore, the objects to be dried on the storage trays (2 1) of each layer are simultaneously blown by dry and warm air, and the degree of drying is uniform, so as to improve the reference case because the flow of the storage box The road moves back and the cold air flows from top to bottom, so that the to-be-dried objects in the upper and lower layers have different degrees of air-drying. 2 · After the work is air-dried, the germicidal lamp (30) is used for sterilization to prevent the contaminated air from continuing to circulate and ensure the safety and hygiene of the dried matter. 3 · When dry and warm air blows the to-be-dried material to take away the water on the surface of the to-be-dried material 9 M240086, it is also possible to blow away the impurities on the surface at the same time, so it can be filtered through the filter (1 5) The operator can take out the filter screen (1 5) and take care of it, so as to ensure the service life of the circulating system such as the condenser, and to clean the surface of the dry matter. Therefore, the original creation, which has several advantages, can improve the lack of custom and is very progressive, and its structure is not found in existing products.
