Embodiment Construction

[0008] (1) Clean the leaves and stems of plants with water; (2). Dry and dehydrate the cleaned materials; (3). Cut the dried leaves and stems into 5-15mm sections; (4). 50%-80% saturated vitamin C aqueous solution is sprayed on the cut leaves and stems to protect the superoxide dismutase in them from being oxidized and lose its activity, and put it into the low-temperature drying pipeline conveyor belt, and ventilate and dry The temperature is controlled below 50°C; (5). The leaves and stems that have been dried at low temperature are crushed through a crushing device, and the temperature of the surrounding environment is kept below 30°C; (6). The crushed feed is packed into a woven bags for packaging.

[0009] Plant leaves and stems include those of burdock; stems and leaves of sorrel; leaves and stems of vermillion, and more.

[0010] In order to improve the drying efficiency, the air pressure of the vacuum conveyor ventilation duct is kept at 10 3 to 10 4 Mpa, that is, l...

Abstract

The invention relates to a method for preparing livestock feed by using stems and leaves of annual plant through low-temperature drying method. The water content of the feed prepared by the low-temperature drying method is kept in the range of 5%-13%, the green appearance of the feed is also maintained, and the most of superoxide dismutase (SOD) and protein (Protein), and various organic active matters in the leaves and stems are not damaged.

Description

technical field [0001] The present invention relates to a method for preparing animal feed, more specifically a method for preparing animal feed with stems and leaves of annual plants using a low-temperature drying method. Background technique [0002] We know that the leaves and stems of plants are rich in various vitamins, organic ketone materials, cellulose, organic active substances, such as superoxide dismutase, leaf protein, antioxidant substances and so on. However, when a large number of plant leaves and stems need to be processed, improper methods, such as high-temperature drying, will cause a large number of active substances to lose their activity. For example, substances such as superoxide dismutase (superoxide dismutase SOD) and leaf protein will coagulate and lose activity of protein substances at a temperature higher than 60° C., especially the loss of activity of superoxide dismutase is a very unfortunate thing. If animals, such as dairy cows, eat a large am...
