Description

Technical Field

[0001] This invention relates to the field of forage processing, and more particularly to a fermentation apparatus for forage processing production. Background Technology

[0002] The process control of forage fermentation mainly revolves around four modules: raw material pretreatment, fermentation parameters, turning and management, and quality testing. The ultimate goal is to promote the reproduction of beneficial microorganisms (such as lactic acid bacteria) and inhibit the growth of harmful bacteria. Moisture control: The moisture content of the raw materials should be controlled at 60%-70%. Excessive moisture can easily lead to spoilage and can be reduced by sun-drying; insufficient moisture will slow fermentation and requires spraying with clean water to replenish it. Particle size: Adjust according to the type of raw material. For raw materials with a high degree of lignification, such as corn stalks and rice straw, crush to 2-3 cm; for soft raw materials such as alfalfa and rye grass, cut to 5-8 cm to avoid poor aeration due to excessive fineness. Material mixing: When the nutrition of a single raw material is unbalanced, it can be mixed in proportion, for example, corn stalks and alfalfa can be mixed in a 3:1 ratio to increase protein content and optimize the carbon-nitrogen ratio.

[0003] Initial fermentation stage: By sealing and maintaining the temperature, the pile temperature is raised to 50-60℃ within 24-48 hours. This temperature can kill most harmful bacteria and insect eggs. High temperature maintenance: Maintain the temperature at 50-60℃ for 5-7 days to promote cellulose degradation. Cooling stage: When the temperature naturally drops to 30-40℃, it indicates that fermentation has entered the later stage, and preparations for discharging or resealing are needed.

[0004] Oxygen control is a crucial step in silage fermentation, primarily employing anaerobic fermentation. Strict air isolation, achieved through methods such as covering with plastic film and compacting the pile, effectively inhibits the growth of aerobic spoilage bacteria, ensuring fermentation quality. If windrow fermentation is used, the integrity of the plastic film seal must be regularly and meticulously checked; any damage must be repaired immediately to prevent air infiltration and fermentation failure.

[0005] However, for most small and medium-sized farmers, directly purchasing factory-produced silage or finished forage is too costly and unaffordable. Therefore, many farmers choose to ferment their own forage to reduce costs.

[0006] Currently, the common method is to use plastic woven bags (commonly known as plastic bags) to hold and ferment the feed. However, in practice, the bags need to be fully opened manually before the feed is filled in one bag at a time. This process is not only difficult and extremely physically demanding, but also inefficient. Farmers often have to bend over and laboriously process each bag of feed, and this inefficient filling method severely restricts overall labor productivity, becoming a major obstacle to the promotion of self-fermentation technology.

[0023] This patent provides multiple parallel solutions; the different descriptions represent improved solutions or parallel solutions based on the basic solution. Each solution has its own unique characteristics. Furthermore, the technical features involved in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other. Fixing methods not described herein can be any type of fixing, such as threaded fixing, bolt fixing, or adhesive bonding.

[0024] Example 1: Referring to all the accompanying drawings; A fermentation device for forage processing, characterized in that, The fermentation apparatus includes a base container 1, which is covered with a multi-purpose cover 2; It also includes a lower film 7 and an upper film 6 inside the pit; The lower membrane 7 inside the pit can be fitted inside the base container 1. The lower membrane 7 inside the pit is square and its area is larger than that of the upper membrane 6. The bottom of the multi-purpose top cover 2 includes a closed edge 4; The upper film 6 has upper holes 9 arranged on it; A one-way exhaust port 8 is arranged on the side of the basic container 1; The forage can be placed in a base container 1 with a lower film 7 covering the pit; it can then be covered and heat-sealed by an upper film 6 and a multi-purpose cover 2. Air can be drawn outwards from the one-way exhaust port 8. The substantial technical effect and its implementation process, i.e., the basic function and non-obviousness, are as follows: Compared to the shortcomings of existing technologies, "the currently common method is to use plastic woven bags, commonly known as plastic bags, to hold feed and ferment it. However, in actual operation, the bag openings need to be fully opened manually before the feed is filled into each bag. This process is not only difficult and extremely physically demanding, but also inefficient. Farmers often have to bend over and spend a lot of time and effort handling each bag of feed. This inefficient filling method seriously restricts overall labor productivity and has become a major obstacle to the promotion of self-fermentation technology."; This patent eliminates the need for bagging. First, a thin film 7 is placed inside the pit and then placed inside the base container 1. Then, the feed is added, followed by the film 6, which is then pressed down with the multi-purpose cover 2. Electricity is applied, and the mixture is heat-sealed. Subsequently, the heat-sealed mixture of the inner film 7 and the film 6 is bonded and heat-sealed to the multi-purpose cover 2 and the base container 1 to form a whole, achieving airtightness; Then, air is extracted through the one-way exhaust port 8 to achieve anaerobic fermentation.

[0025] Example 2: As a further improvement, parallel solution, or optional independent solution, a heating metal sheet 41 is arranged on the closed edge 4 of the multi-purpose cover 2, and the heating metal sheet 41 is connected to an electric wire. Therefore, a seal can be achieved while maintaining a complete seal.

[0026] Example 3: As a further improvement, parallel, or optional independent solution, the multi-purpose cover 2, the heat-sealed body of the lower inner film 7 and the upper film 6, and the base container 1 are arranged vertically as a whole. The heat-sealed body of the lower inner film 7 and the upper film 6 is respectively bonded and heat-sealed to the multi-purpose cover 2 and the base container 1 to form a whole. The solution provided in this example innovatively combines heat sealing and sealing, and is quick, convenient, safe, and fast to use.

[0027] Example 4: As a further improvement, parallel solution, or optional independent solution, a pressure gauge is arranged on the multi-purpose cover 2. During evacuation, the upper hole 9 allows air to be drawn from the gaps between the forage compartments. The one-way evacuation port 8 is a one-way valve.

[0028] Innovatively, each of the above effects exists independently, yet a single structure can be used to combine the results.

[0029] It should be noted that the multiple solutions provided in this patent include their own basic solutions, which are independent of each other and do not restrict each other. However, they can also be combined with each other without conflict to achieve multiple effects.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
