Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of grain steaming machines, and particularly relates to a grain steaming machine for herbal wine production and a production process thereof. BACKGROUND

[0002] In the production of herbal wine, the key step of steaming grains is generally carried out by using a high-efficiency continuous grain steaming machine. The raw materials are fully gelatinized by steam heating, and the steam heating also has the functions of sterilization, removal of raw material odor, and preliminary aging, thereby laying a foundation for the subsequent saccharification and fermentation step.

[0003] Traditional grain steaming machines generally use fixed steam pipes to deliver steam into the grain steaming chamber. The steam injection beam is a fixed structure, and its position cannot be adjusted. When the spreading thickness of the grain raw materials on the conveying belt is adjusted due to differences in raw material categories, the steam cannot accurately act on the surface of the raw materials. If the distance between them is too far, the steam may condense prematurely, resulting in waste of heat energy. If the distance is too close, the raw materials may be locally overheated, affecting the cooking quality. At the same time, the existing equipment only relies on the turning rollers to turn the materials to assist in cooking. There is no special structure for directional delivery of steam to the interior of the raw materials, and there is no suitable air-permeable gas supply assembly. In the steaming stage that is not suitable for turning (such as after the raw materials are gelatinized, and during the water retention and shaping period), the raw materials may have poor uniformity in surface and internal steaming, and the overall steaming efficiency may be low.

[0053] It should be noted that the steaming machine for producing herbal wine has the following process flow:

[0054] S1: Put all raw materials for brewing herbal wine, especially organic rice and herbal accessories (herbal accessories can be matched with medlar, huangji, radix rehmanniae preparatae, cistanche, astragalus, ginseng, mulberry, poria cocos, cornus officinalis, ophiopogon, raspberry, licorice, cassia and gardenia as needed) into the soaking barrel 11, add water to 5-10 cm higher than the raw materials, and soak for treatment. The detailed process is as follows: Put the cereal raw materials for brewing herbal wine into the soaking barrel 11, add water to the liquid level above the raw materials, and soak for 4-8 hours. The core purpose of this step is to make the raw materials fully absorb water, which lays the foundation for starch gelatinization during subsequent cooking. The volume of the soaking barrel 11 should be designed to match the processing capacity of the subsequent steaming machine to ensure continuous supply of raw materials.

[0055] S2: After soaking is completed, open the discharge valve of the soaking barrel 11, and immediately start the elevator between the soaking barrel 11 and the feeding barrel 10 to transport the water-absorbed raw materials to the feeding barrel 10 above the steaming bin 2. The detailed process is as follows: When the raw materials are soaked to the specified standard, open the discharge valve at the bottom of the soaking barrel 11, and at the same time, start the elevator between the soaking barrel 11 and the feeding barrel 10. The elevator vertically transports the water-absorbed raw materials to the feeding barrel 10 located directly above the steaming bin 2 for temporary storage. The discharge port of the feeding barrel 10 is aligned with the feeding end of the steaming bin 2 to provide support for uniform distribution of raw materials in the subsequent process.

[0056] S3: open the discharge valve of the feed bucket 10, make the raw materials evenly fall on the conveying belt 3 of the steaming bin 2, adjust the raw material paving thickness by controlling the feeding speed, at the same time, adjust the height of the steam jet beam 4 through the adjusting mechanism 9, so that the steam jet beam 4 is always kept at an appropriate distance from the raw material paving height, and the steam jet beam 4 can accurately spray high-temperature steam to the surface of the raw material. The detailed process is as follows: open the discharge valve of the feed bucket 10, control the falling speed of the raw materials through the valve opening, and make the raw materials evenly fall on the surface of the conveying belt 3 driven by the conveying roller on the rack 1. At the same time, the operator adjusts the height of the adjusting plate 91 and the steam jet beam 4 through the adjusting mechanism 9 to adjust the paving thickness of the raw materials: turn the hand wheel at one end of the horizontal shaft two 92 to drive the horizontal shaft two 92 to rotate on the side wall of the steaming bin 2. The gears 93 fixed at both ends of the horizontal shaft two 92 are engaged with the rack 94 on the adjusting plate 91, so that the adjusting plate 91 slides vertically along the sliding groove 221 on the connecting plate 22, thereby adjusting the thickness of the raw materials according to the gap between the adjusting plate 91 and the bottom of the steaming bin 2. The adjusting plate 91 is fixedly connected with the steam jet beam 4 through the connecting rod 42, so that the steam jet beam 4 is driven by the adjusting plate 91 and slides along the sliding rail one 431 on the inner surface of the steaming bin 2 through the sliding blocks one 43 on both sides, and the height is finely adjusted through the avoiding slot 222 on the connecting plate 22, so that the steam jet beam 4 is kept at an appropriate distance from the surface of the raw materials, avoiding the condensation of steam due to too far distance or local overheating due to too close distance. At this time, the conveying belt 3 is started synchronously to smoothly send the raw materials into the steaming bin 2, and the plurality of turning rollers 23 in the steaming bin 2 are turned to continuously turn the raw materials on the conveying belt;

[0057] The steam pipe 8 starts to supply high-temperature steam at this time, a part of the steam is delivered to the steam jet beam 4 through the hose 81, and then is accurately sprayed to the surface of the raw materials through the array of nozzles 41 at the bottom of the steam jet beam 4, thereby completing the heating of the raw materials. The hinged cover plate 21 on the steaming bin 2 can be closed at this stage to reduce steam leakage.

[0058] S4: start the reciprocating assembly 53 to drive the cross bar 51 to reciprocate along the sliding rail, drive the air permeable rod 511 to continuously embed into the raw material layer, and after the connecting rod 54 slides with the cross bar 51 and separates from the embedding cylinder 62, the high-temperature steam enters the connecting rod 54 through the embedding cylinder 62, then is delivered to the air permeable rod 511 through the cross bar 51, and is sprayed from the air permeable hole to the inside of the raw materials, thereby realizing the synchronous steaming of the surface, the detailed process is as follows: at the same time of the surface steam spraying, the fixed servo motor 72 output end drives the linkage shaft 7 to rotate, the linkage shaft 7 and the bevel gears 71 fixed on the horizontal shaft one 531 are engaged with each other, the power is transmitted to the horizontal shaft one 531, and the horizontal shaft one 531 rotates on the steaming bin 2. The rotating disc 532 on the horizontal shaft one 531 rotates with the shaft, the connecting rod 533 hinged at the non-center position of the rotating disc 532 does circular motion, thereby pulling the cross bar 51 to make horizontal reciprocating motion along the sliding rail two 521 in the steaming bin 2 through the sliding blocks two 52 at both ends.

[0059] The plurality of air-permeable rods 511 vertically communicated on the cross rod 51 move synchronously with the cross rod 51 and continuously embed in the raw material layer. Meanwhile, another steam transported by the steam pipe 8 enters the sleeve 61 of the air guide 6 through the conduit 82, the bottom end of the embedding cylinder 62 fixed in the sleeve 61 is provided with an air hole 621, and the communication rod 54 vertically communicated at both ends of the cross rod 51 always slides in the sleeve 61. When the embedding cylinder 62 is located in the communication rod 54, the inner wall of the communication rod 54 closes the air hole 621, and when the communication rod 54 is separated from the embedding cylinder 62, the steam continuously enters the inner cavity of the communication rod 54 through the air hole 621, and then is distributed to each air-permeable rod 511 through the cross rod 51, and finally is sprayed from the air-permeable hole to the inside of the raw material, realizing synchronous and uniform cooking of the inside and outside of the raw material and effectively avoiding the problem of traditional cooking of the outside being cooked and the inside being raw.

[0060] S5: The raw material cooked to maturity is transported to the end of the steaming bin 2 by the conveying belt 3 and falls into the cooling machine 12 for cooling and heat dissipation until the temperature of the raw material is reduced to 25-30 DEG C. The detailed process is as follows: when the raw material is cooked to maturity, the conveying belt 3 has already transported it to the end of the steaming bin 2, and the raw material naturally falls into the cooling machine 12 fixed at the other end of the steaming bin 2. The cooling machine 12 quickly cools the high-temperature raw material by the built-in heat dissipation fan in cooperation with the stirring roller 23 in the steaming bin 2. This temperature interval can avoid the inactivation of the subsequent distiller's yeast due to high temperature and at the same time provide a suitable environment for saccharification reaction.

[0061] S6: The distiller's yeast is uniformly stirred into the cooled raw material, and after the saccharification and fermentation process is completed, distillation treatment is carried out, and finally the herbal base liquor is obtained. The detailed process is as follows: the cooled raw material is transported by the conveying belt 3, and then the distiller's yeast is stirred in by the stirring roller 23. After sealing, saccharification and fermentation are carried out. After fermentation is completed, the fermented fermented grains are sent into the distillation equipment for distillation, and the herbal base liquor is obtained by condensation collection.

It should be pointed out that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which belong to the protection scope of the present application.
