Moringa oleifera leaf drying method

Abstract

The present invention discloses a moringa oleifera leaf drying method. The method comprises the following steps: (1) fresh moringa oleifera leaves are sent into a material distributing bin of a microwave drying device to conduct mechanical material distribution, and the moringa oleifera leaves are spread horizontally on a conveyor belt of the microwave drying device; (2) the distributed moringa oleifera leaves are transferred into a microwave cavity of the microwave drying device, the microwave is used to conduct drying, and at the same time, a dehumidifier is used to discharge moisture in the cavity of the microwave drying device; and until the moringa oleifera leaves are dried into a water content of 0.5%-3%, and the materials can be discharged at a material discharge temperature of 45-55 DEG C; and (3) the treated moringa oleifera leaves by the step (2) are sent into an ultrafine crusher to conduct crushing, and then the crushed materials are inspected and the inspected materials are packaged to obtain dried moringa oleifera leaf finished products. The drying method is short in time, simple in processes and high in efficiency. The dried moringa oleifera leaf finished products have basically unchanged color, are pure in color and luster, and less in nutritional active ingredient damage, and the obtained moringa oleifera leaf powder is high in nutritional quality.

Description

technical field [0001] The invention belongs to the technical field of microwave drying, and in particular relates to a method for drying leaves of Moringa oleifera. Background technique [0002] Moringa, also known as the drumstick tree, belongs to the Moringa family of the cauliflower order. The seeds and leaves of Moringa are rich in nutrients. Moringa is the most nutritious tree in the world. The leaves and pods of Moringa contain various minerals, vitamins, 20 kinds of amino acids, 46 kinds of antioxidants, 36 kinds of natural anti-inflammatory substances and minerals. Therefore, Moringa Wood is also known as "miracle tree", "mother's best friend" and "medicine treasure chest". Moringa leaf is a high-calcium plant product. The calcium content is more than 4 times that of milk. In addition, it also contains high potassium, iron, zinc and other trace elements, and contains protein and amino acids similar to soybeans. In Africa, it is called the milk of the poor; in Indi...
