Description

Technical Field

[0001] This utility model belongs to the field of liquor distillation technology, specifically relating to a multi-stage continuous distillation equipment. Background Technology

[0002] In the continuous distillation process of solid-state baijiu, the steam conveyor belt typically adopts a single-layer perforated plate structure, with steam supplied from a single steam chamber at the bottom and evenly distributed. However, the existing technology has the following drawbacks: First, the steam penetration is uneven. Because the material is directly pressed onto the perforated plate, some holes are easily blocked by material particles, resulting in uneven steam distribution and significant local heating differences in the material, with temperature differences reaching ±10℃, which affects distillation efficiency and the stability of the liquor quality. Utility Model Content

[0003] The purpose of this invention is to overcome the problem that uneven steam penetration affects the distillation efficiency and the stability of the liquor in existing continuous distillation equipment for baijiu, and to provide a multi-stage continuous distillation equipment with uniform steam penetration in the steam conveyor belt.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A multi-stage continuous steam distillation apparatus includes a mash conveying mechanism, which comprises a conveyor belt, a braided structure, and a drive mechanism. The conveyor belt is arranged in a closed loop and has a number of steam holes evenly distributed on its surface. The conveyor belt is used to convey the mash along one side. The braided structure includes a braided layer made of metal wire and air vents formed in the gaps between the braids. The braided layer is arranged in a closed loop on the outer surface of the conveyor belt. The drive mechanism is used to drive the conveyor belt to rotate circumferentially.

[0006] Compared with the prior art, the multi-stage continuous steam distillation equipment of this utility model adopts a double-layer conveying structure for the mash conveying mechanism, which is composed of a metal wire braided layer added to the surface of the conveyor belt. The metal wire braided layer is elastic and can be tightly attached to the outer surface of the conveyor belt in a wrapping manner, which significantly improves the uniformity of steam distribution. The local temperature difference of the mash material is reduced from ±10℃ to ±1.5℃. At the same time, it effectively prevents the material from clogging the steam holes, enhances the heating uniformity of the mash, and improves the distillation efficiency and the stability of the liquor quality.

[0007] Furthermore, the woven structure is woven with an outer surface that has a three-dimensional wave structure. This design increases the contact area between the mash and the steam by about 20%, significantly improving the extraction efficiency of flavor substances and making the flavor of the liquor purer and more harmonious.

[0008] Furthermore, the metal wire is made of stainless steel with a diameter φ of 0.3 to 0.5 mm. The braided structure is woven into a three-dimensional wave structure with a wave height of 3 mm and a wave pitch of 10 mm. The thickness of the braided layer is 2-3 mm. This design gives the braided layer excellent air permeability. The stainless steel braided layer is corrosion-resistant and not easily deformed, increasing the equipment lifespan by more than 50%. The precisely designed wave parameters ensure optimal looseness of the mash layer, reducing steam permeation resistance by 40%. Combined with the thin 2-3 mm braided layer, it maintains structural stability while enabling rapid steam diffusion, ultimately controlling the temperature difference of the mash within ±1.5℃ and increasing distillation efficiency by more than 15%.

[0009] Furthermore, the conveyor belt is a tracked structure, comprising several track plates, links connecting adjacent track plates, and drive shafts and driven shafts located at both ends and drivingly connected to the track plates. The steam holes are located on the track plates. The track plates are made of metal. With this configuration, the conveyor belt adopts a metal tracked structure, consisting of track plates with steam holes, links, and drive and driven shafts. The metal material ensures structural stability under high-temperature conditions, increasing the lifespan by more than 2 times compared to traditional conveyor belts. The modular track plate design allows for individual replacement of damaged parts, reducing maintenance costs by 40%. The link connection method gives the conveyor belt flexible bending capabilities, adapting to the layout of distillation equipment with different curvatures, resulting in good performance.

[0010] Furthermore, the track plate is made of stainless steel; the track plate thickness is 1.5-2mm, the diameter of the steam holes is φ1.0-1.5mm, the opening rate of the steam holes on the track plate is 25%-30%, and the steam holes are arranged in a quincunx pattern. With this design, the stainless steel track plate has good corrosion resistance and the heat conduction efficiency is improved by 20%. The 1.5-2mm thickness ensures structural rigidity while reducing the load on the equipment. The quincunx arrangement of the steam holes effectively improves the steam penetration efficiency. Combined with the optimal opening rate of 25%-30%, it avoids mash leakage and ensures uniform steam penetration, resulting in a distillation efficiency that is more than 18% higher than that of conventional perforated plates.

[0011] Furthermore, the fermented mash conveying mechanism is equipped with a vibrator, which is used to vibrate the conveyor belt when it turns downwards. The vibrator operates at a frequency of 10Hz and an impact force of 200-300N, automatically vibrating for 10 seconds every 30 minutes. With this setting, the fermented mash residue adhering to the track plate and woven layer is effectively removed through precise mechanical vibration, ensuring that the steam vents maintain a patency rate of over 95% for a long time. Actual tests show that these vibration parameters can thoroughly clean the pores while avoiding damage to the metal structure. Combined with automatic control, the downtime cleaning cycle is extended from 8 hours to 72 hours.

[0012] Furthermore, the underside of the mash conveying mechanism is equipped with an elastic scraper and a collection trough. The elastic scraper is made of silicone material, and the angle between the woven layers of the elastic scraper is 40°-60°. The outer edge of the elastic scraper is tightly attached to the woven layer to scrape the mash residue remaining in the woven layer into the collection trough. With this configuration, the underside of the mash conveying mechanism is equipped with an elastic scraper and a collection trough made of silicone material. By tightly attaching the scraper to the woven layer at an angle of 40°-60°, residual mash can be efficiently scraped without damaging the metal woven structure. While maintaining a stable scraping force, the wear rate of the woven layer is reduced by more than 80%. The optimized tilt angle increases the scraping efficiency by 50%. Combined with the collection trough, automatic mash recovery is achieved, which can reduce raw material loss. Moreover, this cleaning method does not require machine shutdown for cleaning, allowing the equipment to operate continuously for long periods.

[0013] Furthermore, it also includes a steam conveying module and a vapor collector located above the conveyor belt. The steam conveying module is used to deliver steam to the steam holes and flow through the mash to form vapor. The vapor collector includes, in sequence along the conveyor belt conveying direction, a head vapor collector, a high-quality wine vapor collector, and a tail vapor collector. The conveyor belt is provided with, in sequence along the conveying direction, a feeding area, a head area corresponding to the head vapor collector, a high-quality wine area corresponding to the high-quality wine vapor collector, and a tail area corresponding to the tail vapor collector.

[0014] Furthermore, the conveyor belt is arranged in a closed loop, divided into an upper conveyor belt and a lower conveyor belt. The steam conveying module is located below the upper conveyor belt. The steam conveying module includes a feeding steam chamber corresponding to the feeding area, a head steam chamber corresponding to the head area, a high-quality liquor steam chamber, and a tail steam chamber corresponding to the tail area. Each steam chamber is equipped with an independent automatic regulating valve and a pressure sensor. Through this arrangement, each steam chamber independently supplies steam to different distillation stages, and is equipped with intelligent regulating valves and pressure monitoring systems to achieve precise control of the distillation process. This design ensures that the mash receives the most suitable steam conditions at different distillation stages, and the steam parameters in each area can be automatically adjusted in real time according to the state of the mash. This ensures the purity and harmony of the liquor flavor, significantly improves the yield of high-quality liquor, and optimizes overall energy utilization efficiency.

[0015] Furthermore, along the conveying direction of the upper conveyor belt, there are six feeding steam chambers, two head steam chambers, five premium steam chambers, and five tail steam chambers. The automatic regulating valves for each feeding steam chamber are F1, F2, F3, F4, F5, and F6, and the pressure sensors for each chamber are P1, P2, P3, P4, P5, and P6. The steam pressure of automatic regulating valve F1 is 6 kPa, the steam pressure of automatic regulating valve F2 is 8 kPa, and the steam pressure of automatic regulating valve F3 is 10 kPa. The steam pressure of automatic regulating valve F4 is 12 kPa, the steam pressure of automatic regulating valve F5 is 14 kPa, and the steam pressure of automatic regulating valve F6 is 16 kPa; the automatic regulating valves for each distillation head steam chamber are F7 and F8, and the pressure sensors for each distillation head steam chamber are P7 and P8, respectively. The steam pressure of automatic regulating valve F7 is 10 kPa, and the steam pressure of automatic regulating valve F8 is 11 kPa; the automatic regulating valves for each premium distillation head steam chamber are F9, F10, F11, F12, and F13, respectively. The pressure sensors in the wine steam chambers are P9, P10, P11, P12, and P13. The steam pressure of automatic regulating valves F10, F11, F12, F13, and F4 is 10 kPa. The automatic regulating valves in each wine tail steam chamber are F14, F15, F16, F7, and F18. The pressure sensors in each wine tail steam chamber are... The steam pressures of automatic regulating valves F14, F15, F16, F17, and F18 are respectively P14, P15, P16, P17, and F18, with pressures of 10 kPa, 11 kPa, 12 kPa, 13 kPa, and 14 kPa. This configuration, with multiple steam chambers along the upper conveyor belt equipped with independent regulating valves and pressure sensors, achieves gradient-based precise steam control during the distillation process. The feeding zone employs a progressive pressurization design, allowing the mash to gradually adapt to the distillation environment; the head zone uses gentle steam to prevent violent boiling; the premium distillation zone optimizes ethanol extraction through multi-stage pressure regulation; and the tail zone uses stepped pressure increases to ensure complete distillation. The intelligent linkage of steam pressure in each zone ensures a smooth heating transition for the mash and allows for customized steam pressure control for different fraction characteristics, resulting in optimal extraction of flavor compounds while ensuring efficient energy utilization.
