Description

Technical Field

[0001] The present invention relates to the technical field of bioengineering, in particular to an amino acid mother liquor drying device. Background Art

[0002] Amino acid mother liquor is a commonly used raw material in bioengineering. It primarily consists of various nutrients, including amino acids, sugars, vitamins, and trace elements. It is typically a byproduct of the fermentation process, but can also be produced through specially designed production processes. Due to its high efficiency, environmental friendliness, and ease of absorption, amino acid mother liquor is widely used in animal husbandry and aquaculture. As an animal feed additive, it can improve feed utilization, boost immunity, and enhance product quality. Furthermore, for plant growth, amino acid mother liquor can be used as fertilizer or as a foliar spray to enhance nutrient absorption. However, before using the amino acid mother liquor, it must be dried. This is because moisture can affect the stability of amino acids and easily cause their degradation. Drying removes moisture, improves their stability, and thus extends their shelf life. Furthermore, drying facilitates the storage and transportation of the amino acid mother liquor, reducing moisture corrosion on packaging containers. Therefore, drying is a crucial step in the production and application of amino acid mother liquor.

It is intended to address the problems of amino acid mother liquor drying equipment in the prior art, such as low degree of integration, large space occupation, and unnecessary process steps. However, during the drying process, the efficiency of amino acid drying is low, and it is not convenient to discharge the dried particles. The particles easily stick to the interior of the drying equipment, requiring manual handling by staff, which reduces the automation rate of the amino acid mother liquor drying equipment.

[0004] Chinese utility model patent publication number CN 207203499 U discloses a spray drying device for amino acid mother liquor and waste liquid. The amino acid mother liquor is dried by spraying, but the amino acid mother liquor is not preheated in advance. As a result, the amino acid mother liquor cannot be quickly evaporated and dried after entering the drying tower, and the drying tower is not convenient for quickly discharging the dried particulate matter.

[0005] During use, the existing amino acid mother liquor drying equipment has a low drying efficiency for the amino acid mother liquor, which increases the processing time and drying cost of the amino acid mother liquor. It is not convenient to quickly discharge the dried particles, and manual cleaning is required by staff, which reduces the automation rate of the amino acid mother liquor drying equipment.

[0018] 1.

The pretreatment mechanism includes a reduction motor, and the output shaft of the reduction motor drives the stirring rod to rotate.

[0019] 2. The present invention is provided with a drying mechanism, which can facilitate the drying of the amino acid mother liquor and quickly discharge the dried particulate matter. The drying mechanism includes a drive motor, which drives the rotating rod to rotate and synchronously drives the multiple umbrella plates to rotate. The preheating spray mechanism sprays the atomized mother liquor into the inner cavity of the drying mechanism. The atomized mother liquor first falls into the top umbrella plate for drying, and then falls down in sequence for multiple drying, thereby increasing the drying efficiency. The dried particulate matter is adsorbed on the top of the umbrella plate. The gas-liquid mixture generated during the drying process enters the vacuum condensation mechanism to prevent the particulate matter inside the drying mechanism from regaining moisture. During the rotation of the umbrella plate, the umbrella plate rotates up and down on the inner wall of the support frame. A spring is provided between the umbrella plate and the support frame. The spring supports the umbrella plate so that it can shake. During the shaking of the umbrella plate, the particulate matter is cleaned and enters the bottom of the inner cavity of the drying tank. An electric heating rod is provided on the umbrella plate to heat the umbrella plate so that the amino acid mother liquor falling on the surface of the umbrella plate can be dried. A plurality of through holes are provided on the umbrella plate to facilitate the flow of the mother liquor.

[0020] 3. The present invention provides a preheating spray mechanism, which can facilitate the preheating of the amino acid mother liquor so that it can be quickly dried after entering the interior of the drying mechanism, and the liquid amino acid mother liquor is converted into a mist. The preheating spray mechanism includes a spiral electric heating tube. The mother liquor enters the preheating tube through the liquid inlet head and the second annular tube. The spiral electric heating tube heats the preheating tube to quickly preheat the mother liquor inside the preheating tube. The preheated mother liquor enters the first annular tube. The thermocouple detects the preheating temperature of the mother liquor, and the detected data is transmitted to the central control system. The central control system controls the heating power of the spiral electric heating tube according to the detected temperature. The mother liquor inside the first annular tube is sprayed into the drying mechanism through the connecting tube and the atomizing nozzle. The atomizing nozzle atomizes the mother liquor so that the mother liquor can be quickly dried.

[0021] 4. The present invention is able to facilitate the discharge of particulate matter inside the drying mechanism by setting up a discharging mechanism, so that the staff can collect the materials conveniently. The discharging mechanism includes a stop valve, which is installed at the bottom of the drying mechanism. When the particulate matter needs to be removed, the stop valve is opened to allow the material to enter the pipe body through the feed pipe. The output shaft of the discharging motor drives the spiral rod to rotate, thereby driving the material to rise and enter the discharging pipe. The staff places the collection bucket at the bottom of the discharging pipe to facilitate the collection of the material.

[0022] 5. The present invention is able to facilitate vacuuming the interior of the drying mechanism by setting a vacuum condensation mechanism, so that the evaporated waste liquid vapor inside the drying mechanism enters the vacuum condensation mechanism, and the waste liquid vapor can be condensed to be converted into liquid and can be collected and processed. The vacuum condensation mechanism includes a vacuum fan, which draws air from the inside of the liquid tank through a vacuum tube and a bend pipe to generate a negative pressure inside the liquid tank. The liquid tank draws the evaporated gas-liquid mixture from the drying mechanism through the exhaust pipe. After the gas-liquid mixture enters the interior of the liquid tank, the gas-liquid mixture contacts the inner wall of the liquid tank. The first heat dissipation jacket and the second heat dissipation jacket condense the high-temperature gas-liquid mixture to convert it into waste liquid stored in the interior of the liquid tank, and finally discharged through the waste liquid pipe, so that the staff can collect and process the waste liquid.
