Plasma sterilization equipment for ensiling raw materials and method

Abstract

The invention relates to plasma sterilization equipment for ensiling raw materials and a method. The method comprises the steps that a plasma generating device is formed by a high frequency electrode and a ground electrode, and a plasma is generated by excitation of a high frequency power source; a conveyor belt is arranged between the high frequency electrode and the ground electrode, ensiling raw materials to be processed are conveyed to a plasma region, and plasma sterilization treatment is performed. The needle electrode is adopted as the high frequency electrode, two adjacent rows of needle electrodes are arranged in a staggered mode, and the uniform plasma can be generated under the barometric pressure. Meanwhile, the number of working high frequency electrodes, the distance between the high frequency electrode and the ground electrode and the conveying speed of the conveyor belt are controllable, and the treated time and effect can be better and finely adjusted. Most bacterial colonies of the ensiling raw materials can be killed, and with the cooperation of the means of adding lactic acid bacteria, the problems existing in the existing ensilage process are solved. In the working process, the ensiling raw material surface can be etched, fermentation is promoted, and the structure of the feed is softer.

Description

technical field [0001] The invention belongs to the technical field of silage, in particular to a plasma sterilizing equipment and method for silage raw materials. Background technique [0002] The silage technology is to isolate the green fodder from the air to produce organic acid, which is not bad for a long time and can reduce the loss of nutrients. Green fodder not only preserves rich nutrients after silage, but also solves the problem of difficult storage and perishability of fresh grass, and creates conditions for the adjustment of feed for herbivores. In addition, the forage after silage will produce a special fragrance, which can promote the appetite of livestock and improve the quality of livestock products. The silage technology solves the problem of insufficient feed supply in winter in the north and ensures the year-round supply of feed. [0003] The principle of silage technology is to use the lactic acid bacteria existing in natural plants for anaerobic ferm...

AI Technical Summary

Problems solved by technology

During the fermentation process, it is difficult for lactic acid bacteria to quickly form a dominant flora. There are problems: various bacteria grow and multiply, and the temperature rises rapidly, resulting in a prolonged fermentation preparation period; the pH value cannot be lowered in a short time

Therefore, during the fermentation process, it is easy to cause the loss of nutrients and energy due to the increase of temperature, and also produce pungent smell and poor taste; mold and spoilage bacteria multiply in large numbers during the fermentation process, resulting in local mildew and rot of silage, etc. Situation; there are many miscellaneous bacteria, easy to secondary fermentation after opening the cellar, mold spots will be formed on some sections, and even completely mildewed and rotted
