AI Technical Summary
The existing low-temperature concentration technology of fruit paste cannot achieve continuous dehydration and concentration, and heat is generated during the stirring process, which can easily cause the material to deteriorate and affect the freshness and taste of the food.
A low-temperature concentration device including a material tray, a top cover and a discharge screw is designed. The material tray has a spiral discharge groove. A feed pipe is arranged at the entrance of the discharge groove. The discharge pipe is connected at the center of the discharge groove. The discharge screw is rotatably connected in the discharge pipe. An exhaust pipe is arranged at the center of the top cover. The upper end of the discharge screw is connected to the exhaust impeller located in the exhaust pipe. The material moves slowly through the spiral discharge groove. The rotation of the discharge screw and the extraction of the exhaust impeller jointly achieve moisture volatilization, avoiding large agitation and temperature increase.
Continuous dehydration and concentration of fruit paste is achieved, the material is deteriorated, the freshness and taste of the food is improved, and the dehydration amount is controlled by controlling the speed of the discharge screw.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of food processing and relates to a low-temperature concentration device for fruit paste. Background Art
[0002] Fruit paste needs to reduce water content through low-temperature concentration to form a paste. In the prior art, the water is generally dispersed by stirring. On the one hand, this method cannot continuously feed and discharge materials. On the other hand, the stirring of materials generates heat, which can easily cause the deterioration of some materials and affect the freshness and taste of fruit processed foods. Utility Model Content
[0003] The purpose of the utility model is to provide a low-temperature concentration device for fruit paste in view of the above-mentioned problems existing in the prior art. The technical problem to be solved by the utility model is to realize continuous dehydration and concentration.
[0004] The purpose of the utility model can be achieved through the following technical solutions: a low-temperature concentration device for fruit paste, characterized in that it includes a material tray, a top cover and a discharging screw, the material tray has a spiral discharging trough, a feed pipe is arranged at the inlet of the discharging trough, a discharging pipe is connected to the central outlet of the discharging trough, the discharging screw is rotatably connected in the discharging pipe, the top cover is located above the material tray, an exhaust pipe is arranged at the central position of the top cover, and the upper end of the discharging screw is connected to an exhaust impeller located in the exhaust pipe.
[0005] Furthermore, the bottom surface of the material tray is conical, and the position where the material tray is connected to the discharge pipe is the lowest point of the material tray.
[0006] The material enters the discharge chute from the high point of the material tray and slowly moves along the spiral discharge chute to the discharge pipe. The closer to the discharge pipe, the less moisture the material contains. The material is discharged through the rotation of the discharge screw. In addition, the discharge screw is also connected to the exhaust impeller to evacuate the material tray to accelerate the volatilization of water vapor. In this way, the material will not be greatly stirred and the temperature will not rise due to stirring. In addition, the two trays are conical, and the natural fluidity of the material is better. Controlling the speed of the discharge screw can control the discharge speed and thus the amount of dehydration. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0011] like Figure 1 and Figure 2 The low-temperature concentration device for fruit paste shown in the figure includes a material tray 1, a top cover 2 and a discharge screw 3. The material tray 1 has a spiral discharge trough 8, a feed pipe 4 is provided at the inlet of the discharge trough 8, a discharge pipe 5 is connected to the central outlet of the discharge trough 8, the discharge screw 3 is rotatably connected in the discharge pipe 5, the top cover 2 is located above the material tray 1, an exhaust pipe 6 is provided at the central position of the top cover 2, and the upper end of the discharge screw 3 is connected to an exhaust impeller 7 located in the exhaust pipe 6.
[0012] The bottom surface of the material tray 1 is conical, and the position where the material tray 1 is connected to the discharge pipe 5 is the lowest point of the material tray 1.
[0013] The material enters the discharge trough 8 from the high point of the material tray 1, and slowly moves along the spiral discharge trough 8 to the discharge pipe 5. The closer to the discharge pipe 5, the less moisture the material contains. The material is discharged by the rotation of the discharge screw 3. In addition, the discharge screw 3 is also connected to the exhaust impeller 7 to evacuate the material tray 1 to accelerate the volatilization of water vapor. In this way, the material will not be greatly stirred, and the temperature will not rise due to stirring. In addition, the two trays are conical, and the natural fluidity of the material is better. Controlling the rotation speed of the discharge screw 3 can control the discharge speed to control the dehydration amount.
