Abstract
Description
Technical Field
[0001] This invention relates to the field of fermentation technology, specifically a bark fermentation process. Background Technology
[0002] Bark refers to all tissues outside the vascular cambium of the stem. It is the protective layer around the trunk, that is, the part that can be peeled off the trunk during harvesting or processing.
[0003] Tree bark contains abundant mineral elements, which are beneficial to the growth of flowers and plants. However, it is difficult to fully release the nutrients when using tree bark directly. Therefore, it is necessary to ferment the tree bark before use.
[0004] Currently, the bark is simply boiled and sterilized before fermentation, which leaves the bark's own acidity and lipids intact, thus affecting the subsequent fermentation effect. Moreover, the current method of using only Orchid King as a fermentation solvent results in a limited variety of nutrients in the bark. Summary of the Invention
[0005] In view of this, the purpose of this invention is to propose a bark fermentation process that can remove the acidity and lipids of the bark itself, thereby improving the fermentation effect; and to add probiotics to the base of Lanjunwang (a type of fungus) to increase the nutrients in the bark.
[0006] To achieve the above objectives, the present invention provides a bark fermentation process, wherein step one is to select bark for pretreatment such as insecticidal, sterilization, and crushing;
[0007] Step 2: Deep treatment of the pretreated bark, including acid removal and degreasing;
[0008] Step 3: After diluting the fermentation solution with water in the bucket, add the deeply treated bark and begin the fermentation process;
[0009] Step 4: Real-time temperature monitoring during fermentation;
[0010] Step 5: Turn the pile during fermentation;
[0011] Step Six: After fermentation is complete, perform screening, and control the temperature during the screening process;
[0012] Step 7: The selected bark is oxidized and then packaged for shipment.
[0013] As a preferred technical solution of the present invention, one of pine bark, willow bark, chestnut bark or fir bark is selected to implement steps one to seven; wherein the pine bark is treated by sun exposure or boiling water with the addition of insecticide for insecticidal and sterilization treatment; while the willow bark, chestnut bark and fir bark are treated by boiling water with the addition of insecticide for insecticidal and sterilization treatment.
[0014] As a preferred technical solution of the present invention, in step one, the bark is crushed by using a stainless steel crusher in two modes: coarse crushing and medium crushing, so that the bark is in 2-3 cm blocks.
[0015] As a preferred technical solution of the present invention, in step two: sodium hydroxide and alkali are added to hot water and diluted and mixed, then granular bark is added, and the mixture is soaked for 24 hours before being taken out. The ratio of hot water, sodium hydroxide and alkali is 200:4:3, the hot water temperature is between 70-75℃, and the concentration of sodium hydroxide is 5%.
[0016] As a preferred technical solution of the present invention, in step three: the fermentation solution is made of lactobacillus acidophilus, bifidobacterium thermophilus, or Gram-positive cocci such as streptococcus faecalis and Lanjunwang, and the ratio of fermentation solution to water is 1:300, and the fermentation cycle is 1 month.
[0017] As a preferred technical solution of the present invention, in step four: a temperature sensor is installed in the fermentation tank, the temperature monitored by the temperature sensor is set to be between 45-50℃, and a signal transmission module is connected, and the signal transmission module is connected to a buzzer.
[0018] As a preferred technical solution of the present invention, in step five: the pile is turned over once after seven days of fermentation, and a total of four times during the entire fermentation period. Through the turning during the fermentation process, the blocky bark becomes bark mixed with fibrous and granular materials.
[0019] As a preferred embodiment of the present invention, in step six: the fibers and particles mixed in with the bark are separated by a vibration screening machine, and the screening process is carried out at 30°C.
[0020] As a preferred embodiment of the present invention, in step seven: the bark that has been screened and is in both fibrous and granular form is placed in a sealed box for oxidation and drying, and then packaged.
[0021] The beneficial effects of this invention are: the bark fermentation process, by performing a series of pretreatments and deep treatments on the selected bark before fermentation, can effectively remove substances in the bark that are incompatible with the fermentation solution, thereby improving the effect of subsequent fermentation and decomposition; and because probiotics are inoculated on the original basis, the nutrients in the bark after fermentation are increased, which is very beneficial to the growth of flowers and plants. Attached Figure Description
[0022] The accompanying drawings are provided to further illustrate the invention and form part of the specification. They are used in conjunction with embodiments of the invention to explain the invention and do not constitute a limitation thereof. In the drawings:
[0023] Figure 1This is a process flow diagram of a bark fermentation process according to the present invention. Detailed Implementation
[0024] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0025] Example: A bark fermentation process of the present invention includes the following steps:
[0026] Step 1: Select tree bark for pretreatment such as insecticide killing, sterilization, and crushing;
[0027] Step 2: Deep treatment of the pretreated bark, including acid removal and degreasing;
[0028] Step 3: After diluting the fermentation solution with water in the bucket, add the deeply treated bark and begin the fermentation process;
[0029] Step 4: Real-time temperature monitoring during fermentation;
[0030] Step 5: Turn the pile during fermentation;
[0031] Step Six: After fermentation is complete, perform screening, and control the temperature during the screening process;
[0032] Step 7: The selected bark is oxidized and then packaged for shipment.
[0033] Select one of the following: pine bark, willow bark, chestnut bark, or fir bark, and implement steps one through seven. Pine bark is treated by sun exposure or boiling in water while adding insecticide for insecticidal and sterilization treatment. Willow bark, chestnut bark, and fir bark are treated by boiling in water while adding insecticide for insecticidal and sterilization treatment.
[0034] Sun-drying pine bark can kill insect eggs and termites contained within it. High-temperature steaming combined with sun-drying can remove pests and bacteria remaining on pine bark, as well as pests and bacteria from willow, chestnut, and cedar bark.
[0035] In step one, the bark is crushed using a stainless steel crusher in two modes: coarse and medium crushing, resulting in 2-3 cm pieces.
[0036] After the above-mentioned insecticide and sterilization treatment, the bark will have reduced hardness. When crushed in a stainless steel crusher, what previously required one coarse crushing and two medium crushings to form 2-3 cm pieces of bark can now be accomplished with just one coarse crushing and one medium crushing. The larger pieces of bark in the 2-3 cm shape will then ferment and decompose more fully.
[0037] In step two: add sodium hydroxide and alkali to hot water, dilute and mix, then add granular bark, soak for 24 hours and then take it out. The ratio of hot water, sodium hydroxide and alkali is 200:4:3, the hot water temperature is between 70-75℃, and the concentration of sodium hydroxide is 5%.
[0038] Tree bark is a slightly acidic substance and also an organic matter. If processed properly, it is perfect for use as fertilizer. However, before using it, it needs to be neutralized and its acidity reduced by alkali. Reducing its acidity will improve the degradation and absorption of the tree bark.
[0039] Tree bark contains lipids, and the presence of lipids can affect the water retention performance of the bark when it is fermented and used as soil for flowers and plants. Therefore, it is necessary to remove the lipids from the bark by adjusting the parameters in step two.
[0040] In step three: the fermentation solution is made of lactobacillus acidophilus, bifidobacterium thermophilus, or Gram-positive cocci such as streptococcus faecalis and Lan Junwang, and the ratio of fermentation solution to water is 1:300, and the fermentation cycle is 1 month.
[0041] The newly added Lactobacillus acidophilus, Bifidobacterium thermophilus, or Gram-positive cocci such as Enterococcus faecalis can enhance the metabolic function of flowers and plants, improve photosynthesis, promote seed germination, root growth and seedling development, and make leaves thick and glossy. They can also utilize solar heat energy to synthesize antioxidants, amino acids, sugars, and various physiologically active substances to promote plant growth and improve the ability to absorb nutrients.
[0042] Fermentation can promote the saccharification of bark, and the temperature during the entire fermentation cycle must be controlled between 45-50℃.
[0043] In step four: Install a temperature sensor inside the fermentation tank, set the temperature sensor to monitor a temperature between 45-50℃, and connect it to a signal transmission module, which is then connected to a buzzer.
[0044] During fermentation, a temperature sensor monitors the fermentation temperature in real time. When the monitored temperature exceeds or falls below the set temperature threshold, it outputs a signal to the signal transmission module, which then controls a buzzer to sound an alarm, prompting staff to take corresponding cooling or heating measures.
[0045] In step five: the pile is turned over once after seven days of fermentation, and a total of four times during the entire fermentation period. Through the turning during the fermentation process, the blocky bark becomes bark mixed with fibrous and granular materials.
[0046] Turning the compost pile shortens the entire fermentation cycle and promotes temperature rise during fermentation. High temperatures kill pathogens, insect eggs, and weed seeds, which helps improve the maturity of the compost and promotes the rapid conversion of organic matter into humus.
[0047] In step six: the fibers and particles mixed in with the bark are separated by a vibrating screening machine, and the screening process is carried out at 30°C.
[0048] To maintain a generally uniform shape and improve the visual appeal for customers.
[0049] In step seven: the fibrous and granular bark, after screening, are placed separately in sealed boxes for oxidation and drying before being packaged. After packaging, they are released to the market for purchase by users.
