Example Embodiment

[0088] Example

[0089] a) Start the first central control box 8. After the preheating is completed, spread the cut and flattened alfalfa raw materials on the conveyor belt 2 through the distributor 1 and make them pass through the high temperature drying chamber 5 at a uniform speed; It is 5cm.

[0090] The alfalfa raw material origin is Baotou, Inner Mongolia.

[0091] b) When the alfalfa raw material passes through the high-temperature drying chamber 5, the first stage of high-temperature drying is performed.

[0092] During the drying process, the gas in the high-temperature drying chamber 5 enters the electric heating box 12 through the return air pipe 14 under the pressurization of the high-pressure fan 13, and then enters the slit-type air flow impact through the air distribution box 10 and the air duct 9 in turn. The pipe 4 is sprayed into the high-temperature drying chamber 5 through the airflow nozzle 24 to realize the circulating heating of the alfalfa raw materials and at...

Abstract

The invention belongs to the technical field of alfalfa drying and particularly relates to a technology and equipment for drying alfalfa under combination of gas jet impacting and normal-temperature ventilating. The equipment for drying alfalfa under the combination of gas jet impacting and normal-temperature ventilating includes a stepping motor (3) and a raw material conveying device and further comprises a gas circulation heating and dehumidifying device, a normal-temperature ventilating device and a central control device. The technology for drying alfalfa under the combination of gas jet impacting and normal-temperature ventilating includes first-stage high-temperature drying and second-stage normal-temperature drying. A large amount of arranged gas jet impacting pipes (4) are adopted in the drying equipment, it can be ensured that an even jet impacting plane is formed, and the drying consistency of alfalfa is improved; and two-stage drying is adopted as the technological principle, and the prominent problems that drying is not even, losses of nutrient substances are high, and the handling amount is low during mechanical drying of alfalfa can be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of alfalfa drying, and in particular relates to a process and equipment for drying alfalfa by gas jet impingement combined with normal temperature ventilation. Background technique [0002] Alfalfa (Medicago Sativa, L) is a perennial leguminous plant with the reputation of "grass queen". It is a very good vegetable protein feed material with high protein content and highly digestible fiber, and contains vitamins, carrots various trace elements. [0003] Different from gramineous forages, alfalfa is composed of stems and leaves after mowing, the ratio of stems to leaves is 1.5-2.5, the crude protein content in leaves is 1-1.5 times higher than that in stems, and the crude fiber content is more than 50% less than that in stems. The surface of alfalfa has a bright waxy layer, which can prevent the loss of water from the alfalfa plant. In actual production, the cut alfalfa is usually flattened to increase the d...
