Description

Technical Field

[0001] This utility model belongs to the field of distillers' grains drying and processing technology, specifically involving a drying line using air-pressure drying and distillers' grains parent material mixing method. Background Technology

[0002] Distillers' grains, a byproduct of brewing, have a high moisture content (typically >60%), are highly viscous, and are prone to spoilage. The drying process presents the following technical challenges:

[0003] Blockage risk: Highly viscous materials are prone to adhering to the inner wall of the equipment or the conveying system;

[0004] High energy consumption: Evaporation of moisture requires a large amount of heat energy, and traditional drying methods are inefficient;

[0005] Quality control is difficult: high temperatures may cause sugar caramelization or protein denaturation;

[0006] Environmental pressure: Exhaust gas emissions contain dust and moisture, requiring environmental treatment;

[0007] Existing technical challenges of hot air dryers include: High energy consumption: Traditional hot air dryers mostly use electrically heated conveyor belts, resulting in relatively high energy consumption. Especially during long-term operation, electricity consumption can become a significant cost; it can also lead to uneven drying, affecting the drying effect and potentially damaging some temperature-sensitive fruits and vegetables. Excessive noise: Hot air dryers generate noise and vibration during operation, which not only affects the working environment but may also damage the equipment itself. Equipment maintenance costs: Hot air dryers require regular maintenance and upkeep during long-term operation, including cleaning, filter replacement, and circuit inspection. These maintenance tasks require a certain cost and may affect the normal operation of the equipment.

[0008] A published patent, "A Distillery Grains Drying Device," application number CN202220301942.3, application date: February 15, 2022, publication number CN216898120U, publication date: July 5, 2022, provides a device including a drying chamber, a protective mechanism, a heating mechanism, and a transfer mechanism. The protective mechanism is located inside the drying chamber, while the heating mechanism and the transfer mechanism are located on the surface of the drying chamber. This device transports brick-shaped lees to the drying chamber via a conveyor belt. A hydraulic cylinder extends and retracts, moving the receiving box. A motor drives a bidirectional threaded rod to rotate, causing two L-shaped plates to move closer or further apart. This allows multiple L-shaped plates to contact the edges and corners of the brick-shaped lees, thus protecting the four corners and preventing the edges from falling off due to expansion during drying. The drawback is that it only dries brick-shaped lees.

[0009] There is a need to invent a mother-plant method distillers' grains drying line that improves energy efficiency, enables large-scale production, prevents sticking, provides uniform drying effect, and reduces maintenance costs. Utility Model Content

[0023] The steps of the mother plant method for drying distiller's grains:

[0024] (a) The wet lees are fed into the debulking machine 2 through the feed inlet 1 to debulk, and the debulked wet lees are then fed into the dry-wet mixer;

[0025] (ii) The lees are mixed and dried using the parent plant method. The weight mixing ratio of lees is: wet lees 0.8-1.2: dry lees 1-1.5. The wet lees and dry lees after being broken up are mixed in the parent plant mixer, and the mixed wet and dry lees are conveyed to the pre-drying conveyor belt 5-2.

[0026] (III) The pre-drying conveyor belt 5-2 transports the dry and wet lees after mixing the parent material into the pre-drying chamber 5, and the bottom blower 5-1 blows the ambient temperature natural wind into the pre-drying chamber 5 from top to bottom;

[0033] The aforementioned thermal energy fan 8-1 is a low-noise fan, and the air volume range of the thermal energy fan 8-1 is 20,000 to 30,000 cubic meters per hour.

[0034] The weight mixing ratio of the distiller's grains is as follows: Wherein:

[0035] When the moisture content of the dried lees product is 11-13% and the moisture content of the wet lees is 60-65%, the optimal lees weight mixing ratio is: wet lees 1: dry lees 1-1.2.

[0036] When the moisture content of wet distiller's grains is 60%-65%, the optimal temperature setting for the air-source heat pump is 56℃.

[0037] The principles of air-source heat pumped drying of distiller's grains and the air-source hot airflow downward pressure drying method:

[0038] To address the issues of high water content and high viscosity of baijiu lees, which easily cause them to stick to the drying equipment during the drying process, and to ensure that the dried lees have the required water content for storage, a solution is needed.

[0039] Reducing overall viscosity: Undried lees have a high moisture content and high viscosity, making them prone to sticking to equipment during the drying process. In contrast, dried lees have a low moisture content and a relatively loose structure. When mixed with lees, the dried lees can act as a "skeleton" or "filler," reducing direct contact and adhesion between lees particles, thus lowering the overall viscosity of the mixture and mitigating sticking.

[0040] Improved heat transfer efficiency: Dried lees have relatively good thermal conductivity. When mixed with undried lees, they can be more evenly dispersed in the material, allowing heat to be transferred more quickly and evenly within the material. This avoids local overheating or uneven drying, helps reduce the situation where materials stick to the equipment due to excessively high local temperatures, and also speeds up the overall drying process, shortens the residence time of materials in the equipment, and reduces the risk of adhesion.

[0041] Optimized material flowability: The presence of dried distiller's grains improves the flowability of the mixed material. During the drying process, the material flows more smoothly within the equipment, reducing its residence and accumulation on the equipment surface, thereby lowering the likelihood of adhesion.

[0042] Flexible process adjustment: The mixing ratio of dried and undried lees can be flexibly adjusted according to actual production conditions to adapt to lees raw materials with different initial moisture contents, ensuring smooth drying process and reducing adhesion problems.

[0043] Energy consumption control is relatively reasonable: Compared with simply drying high-viscosity undried lees, mixed drying utilizes the physical properties of dried lees, reduces the overall viscosity of the material and the difficulty of drying, and to a certain extent reduces the energy consumption required for drying and improves energy utilization efficiency.

[0044] Improved product quality stability: Mixed drying makes the materials heat more evenly and dry more consistently, which helps to maintain the stability of the nutritional components, color, aroma and other quality characteristics of the distillers' grains products, and reduces quality differences caused by local over- or under-drying.

[0045] Reduced equipment maintenance costs: By reducing material adhesion to equipment, the frequency and difficulty of equipment cleaning and maintenance can be reduced, extending equipment lifespan and reducing production losses and cost increases caused by equipment failures and downtime for maintenance.

[0046] The loose structure of the dried lees allows it to act as a framework for uniform mixing with fresh lees, significantly reducing adhesion to the equipment. After a pre-drying process, the lees are transported to the drying chamber. During pre-drying, a gentle breeze is used to further reduce viscosity and moisture content, thus lowering drying energy consumption, accelerating the overall drying speed, and shortening the material's residence time within the equipment, thereby increasing production capacity. The drying production line can be flexibly adjusted according to actual production conditions; the rated power of the equipment is adjusted based on the amount of lees to be dried. Operation is simple and easy to control; the mixing ratio of wet and dry lees can be adapted to raw materials with different initial moisture contents, ensuring minimal adhesion. Energy consumption control during the drying process is more rational and efficient, improving efficiency and reducing costs compared to direct baking and drying of high-viscosity, high-moisture materials. Mixed drying utilizes the physical properties of the dried lees, reducing the difficulty of drying. It reduces energy consumption required for drying to a certain extent, improving energy utilization efficiency. During the drying process, the equipment can be extended according to the designed length and dimensions based on production capacity.

[0047] Hot airflow downward pressure drying: This method utilizes a stainless steel mesh belt to transport the distiller's grains, employing air source heat and fan airflow downward pressure. The drying chamber is relatively sealed, with hot air from the air source being blown into the chamber from the back through guide vanes. The hot airflow downward pressure is achieved within a sealed enclosure, with an air outlet only located near the bottom at the front. This creates a highly efficient hot airflow downward pressure drying process, preventing the distiller's grains from floating upwards or erratically, thus solving the technical challenge of distiller's grains floating in traditional drying processes. Utilizing air source heat pumps also improves product quality stability, resulting in more uniform drying and maintaining the stable nutritional components, color, and aroma of the distiller's grains. Through the drying of the distiller's grains and the hot air downward pressure method, the stability of the equipment is effectively improved, reducing the frequency and difficulty of cleaning and maintenance, extending equipment lifespan, and minimizing maintenance time and costs due to equipment failure and downtime.

[0048] The drying silo conveyor line consists of a stainless steel wire mesh conveyor belt and nylon rollers. A motor drives the nylon rollers (drive wheels), which in turn use friction to propel the stainless steel wire mesh belt in a continuous cyclical motion, forming a continuous conveying system for distiller's grains. The mesh structure of the stainless steel wire mesh belt allows gas, liquid, or fine particles to pass through, making it suitable for processes such as washing, draining, or high-temperature treatment. The nylon rollers serve as support and guide devices, and are engraved with anti-slip teeth that match the stainless steel wire mesh, reducing belt running resistance, preventing deviation, and ensuring stable conveying of distiller's grains.

[0049] The power principle is as follows: a motor drives a "reduction sprocket mechanism", which in turn drives the conveyor belt. The conveyor belt is divided into a feeding conveyor belt, a mixing conveyor belt, a pre-drying conveyor belt, a drying chamber feeding conveyor belt, a drying chamber stainless steel mesh conveyor belt, and a discharge conveyor belt. The control cabinet controls the sprockets, each conveyor belt, as well as the air source heat pump host and fan.

They are mainly used for real-time weight measurement during material transportation. The dynamic weighing working principle is as follows: when the material moves to the weighing area along the conveyor belt, sensors detect pressure changes and generate electrical signals. These signals are then combined with speed data to calculate the weight per unit time. This is existing publicly known technology; commercially available equipment requires only adaptation modifications in this patent.

[0065] The significant features and technological advancements of this novel distillery lees drying line are:

[0066] The technical approach involves two methods: First, a debulking machine breaks down wet distiller's grains. The dry distiller's grains are then mixed with the wet distiller's grains and fed into a pre-drying chamber. After pre-drying at ambient temperature, the mixture is sent to the main drying chamber. An air-source heat pump provides hot air, which is horizontally blown into the main drying chamber. The hot air is circulated downwards to dry the mixed distiller's grains in a relatively closed loop. This method improves production efficiency and product quality.

[0067] The technical effects achieved are: uniform drying of distiller's grains, energy saving and environmental protection, and preservation of more nutrients.

[0068] The process flow is simple, intuitive, easy to control, and safe to operate.

[0069] The objectives are: to adjust the mixing ratio of the parent material and the drying process parameters, and to control the temperature and hot air flow rate, based on the moisture content of the wet distiller's grains; to select the technical parameters of the equipment, such as the sprocket transmission ratio, according to the different types of distiller's grains to be dried; to dry a large quantity at one time, with low operating and maintenance costs, thus significantly improving economic efficiency.
