The invention discloses a winter bamboo shoot preservation device, please refer to FIG. 1; comprising the following steps:
The annular sleeve 1, the inner side wall of the annular sleeve is provided with a plurality of protruding parts 2, the protruding parts 2 are distributed at intervals along the circumferential direction of the annular sleeve, the protruding parts 2 are provided with a containing cavity, and the part of the containing cavity is provided with a hole site 21; threads are arranged on the outer side of the annular sleeve 1;
A storage object 3 comprising an open receiving chamber; the opening is connected with the thread in an adapting way; the accommodating cavity is used for storing nutrient substances; the storage object can be a bottle structure or a bag body, but is a hard structural member at the opening to ensure the connection stability;
The slow release cotton is adsorbed with nutrient substances, and can be cotton or porous silica gel pieces; when the annular sleeve is sleeved on the winter bamboo shoot body, the slow-release cotton quilt is arranged in the storage cavity, and nutrient substances are released to the winter bamboo shoot body through the hole positions. The annular sleeve can be stably sleeved on the bamboo shoots, then nutrients and nutrition are effectively provided for the roots of the bamboo shoots for a long time through the slow release cotton and the protruding parts, so that nutritional ingredients required in long-time preservation of the bamboo shoots are provided, main nutritional substances of the annular sleeve mainly comprise soil in a picking place, and the mixture of salt water and citric acid is added to further inhibit the microorganism propagation environment, so that winter bamboo shoots are better preserved. The annular sleeve and the protruding part are embedded in the root part, so that the edible part of the winter bamboo shoots is not damaged, and nutritional ingredients can be optimally supplemented for the winter bamboo shoots; the storage object is in threaded connection with the annular sleeve, so that other parts of the root can be directly in soil contact, and a multi-angle nutrient flow channel is ensured; the nutrition circulation path of the winter bamboo shoots also comprises epidermis tissues, so that the winter bamboo shoots are supplemented by injection through the convex parts, and the nutrition substances stored in the slow release cotton and the stored articles are different, so that different effects are achieved.
In this embodiment, the annular sleeve 1 is provided with a diversion hole 11 at a position opposite to the protruding part 2, the diversion hole 11 is communicated with the accommodating cavity, and the nutrient substance flows from the diversion hole and is adsorbed by the slow release cotton. That is, the bulge and the opening are communicated through the diversion hole, so that some liquid nutrient medium in the storage object can be guided into the accommodating cavity of the bulge through the diversion hole and then adsorbed by the slow release cotton, and then released to the surface side of the winter bamboo shoots through the slow release cotton; therefore, various liquid nutrient components can be stored in the storage object, and nutrient which cannot be absorbed in the cross section of the root can permeate into the surface skin side from the diversion holes.
In the embodiment, the annular sleeve 1 is formed by splicing a first annular part and a second annular part; the inner side walls of the first ring part and the second ring part are respectively provided with a protruding part. The winter bamboo shoots with various diameters are adapted through the two parts, the winter bamboo shoots are externally fixed through the storage objects, and flexible materials can be preferably adopted; so as to adapt to the uneven surface, and local putrefaction phenomenon can not occur to the root, even if the local putrefaction phenomenon occurs, the root can not be used, and the local putrefaction phenomenon can be directly cut and discarded.
In the present embodiment, the protruding portions are provided at intervals in both the axial direction and the circumferential direction. Can be connected more tightly, and the air infiltration contact is reduced under long-time contact.
Also disclosed is a winter bamboo shoot preservation method, please refer to FIG. 2; the storage device is adopted; the preservation method comprises the following steps:
Picking: picking the winter bamboo shoots while keeping the root area of the winter bamboo shoots; because the winter bamboo shoots grow without exposing the ground surface, the device cannot be directly embedded into the bamboo shoot meat, and because the bamboo shoot meat is soft, contains more water and is crisp, a fixed nutrition input channel cannot be formed; the root is hard in texture, the cells are densely distributed, and the root at the bottom forms a nutrition conveying channel in the process of absorbing nutrition all the year round; thus, only external nutrient maintenance infusion can be performed through the root;
Pretreatment: wrapping winter bamboo shoots by using a net bag, and performing centrifugal vibration to remove sediment to obtain a pretreatment sample; the holes of the net bag are as compact as possible, and because the surfaces of the winter bamboo shoots only contain sediment, the net bags are not covered with other large-particle impurities basically; the net bag is adopted to ensure that winter bamboo shoots cannot collide and crush when vibrating in the vibrating screen, and sediment can be separated out from holes of the net bag; the reason that water is not used for cleaning is that long-time preservation is ensured, the outer skin wrapped by the winter bamboo shoots needs to be reserved, if the outer skin is removed for preservation, the preservation time is extremely shortened due to the change of the environment of the bamboo shoots; the outer skin is tightly wrapped, and partial decay is easy to occur when the skin is dipped in water, so that only sediment is needed to be thrown away, and the microorganism residue in the sediment is reduced;
cutting grooves: removing the net bag of the pretreatment sample, and forming annular cutting grooves at the joint of the root and the winter bamboo shoot skin; cutting grooves at the joint for matching with the annular sleeve for clamping in, and performing jogging and connection;
Root treatment: filling the slow release cotton adsorbed with the nutrient substances into the accommodating cavity of the protruding part; the annular sleeve is sleeved at the root part, and the protruding part is clamped in the annular groove; the receiving chamber is filled with a nutrient substance and the storage member is then screwed onto the annular sleeve. Thus, for a finished product, the pulp part is wrapped by the compact outer skin of winter bamboo shoots, and the microbial environment of which the surface influences preservation is removed as much as possible in the vibration process; for the root, the existing storage objects are in the simulated soil environment, and the nutrient components can be continuously injected into the winter bamboo shoots through the protruding parts, so that the very long-term simulated growth environment can be maintained, the external environment is stable, and the winter bamboo shoots can be stored for a long time.
In the embodiment, the root axial length of 3-5cm is reserved during picking; the annular sleeve has a width of 3cm.
In the embodiment, a layer of foam cotton is wrapped outside the net bag during pretreatment; vibrating the wrapped winter bamboo shoots by a vibrating screen to remove sediment; the vibration frequency is 20-25Hz. The foam cotton can further prevent winter bamboo shoots from breaking and being damaged during vibration, and the integrity of the whole body is ensured. Too high a vibration frequency will lead to internal breakage and too low a frequency will not vibrate sediment well and is therefore the most suitable interval between 20 and 25Hz.
In this example, saline was adsorbed in the slow-release cotton at the time of root treatment; filling soil in the accommodating cavity until no air gap exists, and pouring saline solution and citric acid aqueous solution into the soil; wherein the weight ratio of the saline solution to the citric acid aqueous solution is 1:1, and the weight of the saline solution is not more than 200g. Because the winter bamboo shoots are basically consistent in size, the winter bamboo shoots growing above 2kg can be slowly rotted on the ground, and therefore, 1-1.5kg of winter bamboo shoots can be picked basically for use, the weight is only required to be provided with not more than 200g of saline water, and the saline water solution and the citric acid water solution can be fully absorbed by the winter bamboo shoots or can be stored in the soil of a storage object as long as the saline water solution and the citric acid water solution are unsaturated and crystallized.
In the embodiment, after the annular sleeve and the storage object are connected, the preservative film is embedded between the winter bamboo shoot skins of two adjacent layers, and then the winter bamboo shoot skins are coated; and obtaining a storage sample. Because the outer surface can be damaged and loosened to a certain extent when the winter bamboo shoots are dug and picked, and the phenomenon can be aggravated after vibration, the preservative film is embedded and covered between two layers of overlapped winter bamboo shoot outer skins, then the winter bamboo shoots are wrapped, the whole winter bamboo shoots are covered by the wrapping and the toothpick is provided with ventilation holes; then a storage sample capable of being stored in an air-cooled mode is formed, for winter bamboo shoots, soil environments are simulated below roots, microbial environments are removed above the roots, external environments are isolated by using preservative films, and a freshness locking effect is achieved. The whole can be stored for about 90 days in a normal temperature environment all the time; if the stored sample is stored in a refrigerated environment at 5-10 ℃; can be stored for 180 days without spoilage.
The following table (table 1) is a comparison of the prior art preservation method and the method of the present application;
