Description

Technical Field

[0001] This utility model relates to the field of fermentation tank technology, and in particular to a heat preservation device for a fermentation tank of gardenia. Background Technology

[0002] Gardenia blue, a natural food coloring, is widely used in the food, pharmaceutical, and cosmetic industries. Its core production process involves microbial fermentation. During fermentation, the activity of microorganisms is extremely sensitive to temperature; temperature fluctuations exceeding a certain range can lead to abnormal microbial metabolism, decreased pigment yield, or even fermentation failure.

[0003] Traditional insulation materials are subjected to continuous mechanical stress from tank vibration during long-term operation of fermentation tanks. Simultaneously, they operate in a complex environment of high humidity and fluctuating temperatures. Under the combined influence of these two factors, the insulation materials gradually suffer structural damage, such as visible cracks, localized collapse, or overall deformation. These defects loosen the originally dense internal structure of the insulation material, allowing heat-conducting media like air to penetrate more easily, leading to a continuous decline in insulation performance. Over time, heat loss gradually intensifies, making it impossible to effectively maintain a stable temperature environment in the fermentation tank, which adversely affects the precise control of the fermentation process. Therefore, we propose a fermentation tank insulation device for Gardenia jasminoides. Utility Model Content

[0027] Please see Figure 1-5 This utility model provides a technical solution: a heat preservation device for a fermentation tank of gardenia, comprising:

[0028] Gardenia blue fermentation tank body 1, with an installation groove 9 on the outer surface of the gardenia blue fermentation tank body 1;

[0029] The insulation replacement structure is located on the main body 1 of the Gardenia blue fermentation tank.

[0030] The insulation replacement structure includes insulation cover 1 (2), insulation cover 2 (3), locking plate 1 (4), locking plate 2 (5), connecting plate 6, insert rod 11, and fastening bolts 13. Insulation cover 1 (2) is hinged to insulation cover 2 (3). Insulation cover 1 (2) and insulation cover 2 (3) are closedly installed inside the mounting groove 9. Both insulation cover 1 (2) and insulation cover 2 (3) are interference-fitted with the inside of the mounting groove 9. Locking plate 1 (4) is fixedly connected to the outer surface of insulation cover 1 (2), and locking plate 2 (5) is fixedly connected to the outer surface of insulation cover 2 (3). Both the first plate 4 and the second locking plate 5 have through holes 10 at their tops. The first locking plate 4 and the second locking plate 5 are interlocked and their through holes 10 are connected to each other. The insertion rod 11 is fixedly connected to the inside of the connecting plate 6. The insertion rod 11 is inserted into the through holes 10 on the first locking plate 4 and the second locking plate 5. The outer surface of the insertion rod 11 has a threaded hole 12. The fastening bolt 13 is threadedly connected to the connecting plate 6. The end of the fastening bolt 13 near the insertion rod 11 is threadedly connected to the inside of the threaded hole 12.

[0031] Both heat insulation cover 12 and heat insulation cover 23 have aluminum foil fiberglass cloth 16 fixedly installed inside. Both aluminum foil fiberglass cloth 16 have polyurethane foam filling board 15 fixedly installed inside. Both polyurethane foam filling board 15 have nano aerogel felt 14 fixedly installed inside. Both nano aerogel felt 14 are in close contact with the inside of the mounting groove 9. The joints between the two nano aerogel felt 14 and the two aluminum foil fiberglass cloth 16 are tightly fitted.

[0032] A thermometer 7 and a pressure gauge 8 are fixedly installed on the top of the Gardenia jasminoides fermentation tank body 1. The detection ends of the thermometer 7 and the pressure gauge 8 are located inside the Gardenia jasminoides fermentation tank body 1. A feed pipe is fixedly connected to the top of the Gardenia jasminoides fermentation tank body 1 and communicates with the interior of the Gardenia jasminoides fermentation tank body 1. A discharge pipe is fixedly connected to the bottom of the Gardenia jasminoides fermentation tank body 1 and communicates with the interior of the Gardenia jasminoides fermentation tank body 1. A valve is installed on the discharge pipe.

[0033] Furthermore, when using this device, specifically the gardenia fermentation tank insulation device, insulation cover 1 2 and insulation cover 2 3 are closed and installed in the mounting groove 9 on the outer surface of the gardenia fermentation tank body 1. Insulation cover 1 2 and insulation cover 2 3 are hinged for easy opening and closing. When closed, locking plate 1 4 and locking plate 2 5 are cross-connected, and their through holes 10 are correspondingly connected. Insert rod 11 is inserted through the through hole 10 and then threadedly connected to the threaded hole 12 on the outer surface of the insert rod 11 by fastening bolt 13, so that the connecting plate 6 fixes the insert rod 11, thereby firmly locking insulation cover 1 2 and insulation cover 2 3 on the fermentation tank body.

[0034] The interior of insulation covers 1 and 2 consists of a multi-layer insulation structure composed of nano-aerogel felt 14, polyurethane foam filling board 15, and aluminum foil fiberglass cloth 16. The nano-aerogel felt 14 is in close contact with the mounting groove 9, and its low thermal conductivity reduces heat transfer. The polyurethane foam filling board 15 further fills the insulation space to prevent heat loss. The aluminum foil fiberglass cloth 16 can reflect heat and enhance the structural strength of the insulation cover.

[0035] During the fermentation process, thermometer 7 and pressure gauge 8 monitor the temperature and pressure inside the fermenter in real time. Raw materials are added through the feed pipe, and products are discharged through the discharge pipe and valves.

[0036] The insulation cover 1 (2) and insulation cover 2 (3) are installed using a hinged joint and locking method with insert rod 11 and fastening bolt 13.
