Description

Technical Field

[0001] The present invention relates to the technical field of low-temperature processing, in particular to low-temperature processing equipment for preparing freeze-dried royal jelly powder. Background Art

[0002] Royal jelly freeze-dried powder is a powdered product made from fresh royal jelly by removing moisture through freeze-drying technology. Its core feature is low-temperature dehydration, which can maximize the retention of active ingredients in royal jelly (such as proteins, enzymes, vitamins, fatty acids, etc.), while extending the shelf life and improving stability. During the production process, low-temperature processing equipment for freeze-dried powder is required.

[0003] Most of the existing low-temperature processing equipment for freeze-dried powder requires manual operation to pour royal jelly into a tray, and then place the tray in a freeze dryer. This method has many manual intervention steps, low efficiency, and the risk of contaminating the slurry. Since royal jelly is a thick liquid material, bubbles are easily mixed into the material during loading, and the material may accumulate in the tray with varying thicknesses. During the freeze-drying process, bubbles and materials of varying thicknesses may affect the quality and yield of the freeze-dried powder. Moreover, the active factors in royal jelly have poor heat resistance, and the material will generate heat during mixing and filtering. During the transportation of the royal jelly, heat will destroy some active factors, thereby affecting the nutritional components of the royal jelly freeze-dried powder. In addition, the hotter slurry will affect the rapid freezing speed and prolong the freeze-drying operation time. Therefore, a low-temperature processing equipment for preparing freeze-dried powder from royal jelly is proposed to solve the above problems. Summary of the Invention

A filter is provided at the top of the discharge port to filter out impurities such as animal residues inside the royal jelly.

[0007] Preferably, a columnar cooling body is provided inside the metal cylinder, and a spiral metal tube is provided at the bottom end of the discharge port. The spiral metal tube is provided on the circumferential surface of the metal cylinder. When the royal jelly is filtered, it is transported through the spiral metal tube. The metal cylinder is cooled by the columnar cooling body so that its temperature is about one degree Celsius. The royal jelly is cooled to avoid the heat generated by the royal jelly during preparation and filtration, which affects its activity. At the same time, the royal jelly is pre-cooled in advance to facilitate subsequent rapid freezing and form an ice crystal structure.

[0008] Preferably, a support tube extends from the bottom of the spiral metal tube, and a hose is provided at the extended end of the spiral metal tube. One end of the hose is fixedly connected to the top of the injection port, and an electromagnetic valve is provided inside the injection port.

When the royal jelly is freeze-dried, a certain amount of royal jelly is first delivered to the inside of the filter cylinder 4 through the feed port 24. After the material delivery is completed, the solenoid valve of the feed port 24 is closed, and then the inside of the filter cylinder 4 is pressurized by the compressor 23, so that the royal jelly flows under pressure in the spiral metal tube 26.
