Description

Technical Field

[0001] The utility model relates to the field of spice extraction equipment, in particular to a high-efficiency electric heating spice extraction furnace. Background Art

[0002] The extraction of spices through the extraction furnace usually has the following steps:

[0003] Step 1: Select the appropriate spice raw materials in the preparation stage, ensuring they are of good quality and free of pests, diseases, and impurities. Different spices may require different processing methods. For example, some spices need to be dried to remove excess water and improve extraction efficiency. Choose the appropriate particle size based on the characteristics of the spice and the extraction requirements.

[0004] Step 2: Load the prepared spice raw materials into the extraction vessel of the extraction furnace. The design of the extraction vessel should take into account factors such as the loading method of the raw materials, the flow path of the solvent, and the heat and mass transfer efficiency. Start the heating system of the extraction furnace and raise the extraction temperature to an appropriate range. Heating can increase the diffusion rate of the solvent and the solubility of the spice components, thereby improving the extraction efficiency. At the same time, turn on the stirring device or static mixer to fully mix the solvent and the spice, increase the contact area and mass transfer rate. The stirring speed and time should be adjusted according to the properties of the spice and the extraction requirements to avoid excessive stirring that may cause damage to the spice components or volatilization of the solvent.

[0005] Step 3: After the extraction process is completed, the extract is discharged from the extraction furnace and separated from the spice residue; the separation method can be filtration, centrifugation or distillation, depending on the properties of the extract and subsequent purification requirements;

[0006] In step 2: when the extraction furnace heats the solvent inside it, the heat inside the extraction furnace cannot be in uniform contact with the solvent, resulting in uneven heating of the solvent inside the extraction furnace, thereby reducing the yield of the fragrance.
