Problems solved by technology

The work efficiency of each link is relatively low, the resources cannot be used most effectively, and even the phenomenon of broken links appears
(2) In the whole cold chain logistics, blueberries are not completely guaranteed to be in a suitable low temperature environment, which leads to rot and deterioration of blueberries, which in turn causes direct economic losses
[0006] Although Chinese patent 201410853062.7 discloses a fresh-keeping storage and transportation method for fresh blueberries, it is not a whole-process cold chain for blueberries, which has the following disadvantages: when the fruits are picked, they need to be transported to a cool and dark place, causing bumps in the blueberries during transportation Squeeze, cannot avoid direct sunlight in time, blueberries rot quickly, and work efficiency is low; using traditional pre-cooling methods to preprocess fresh blueberries, the cooling efficiency is low, blueberries are not lowered to a suitable temperature, which is not conducive to fresh storage of blueberries

Embodiment 1

[0048] A method for the whole cold chain of blueberries, specifically comprising the following steps:

[0049] (1) Picking link: such as figure 1 As shown, the workers put the picked fresh blueberries into the picking racks, avoiding the increase in fruit temperature caused by direct sunlight in summer, and keeping the fresh blueberries at about 30°C. The picking rack is a simple picking rack for small berries in the specific embodiment of Chinese patent 201420319775.0.

[0050] (2) Temporary storage link: such as figure 2 As shown, the fresh blueberries picked in the plantations are transported every half an hour, and transported to the temporary storage refrigerators of each plantation. The temperature of fresh blueberry fruit is lowered to below 25°C for transshipment. In the freezer, fix the baskets of fresh blueberries on the transfer tray according to the standard height.

[0051] (3) Transshipment: if image 3 As shown, when the fresh blueberries placed in the ref...

Embodiment 2

[0057] Example 2 Discussion on the Effect of Blueberry Picking Temporary Storage and Transshipment Links

[0058] The maturity period of blueberry fruit is concentrated in June to July, which coincides with the high temperature season, the production period is short and it is not resistant to storage. In previous years, due to the high temperature during the harvest period, the sunburn occurred during the ripening period of the blueberry fruit, causing local softening and discoloration of the fruit, which shows the harm of high temperature to the ripening of blueberry. At the same time, when the picked blueberries are stored at high temperature, the physiological metabolism of the fruit such as respiratory intensity, transpiration, and aging deterioration are accelerated, and the high temperature of 28-30°C is conducive to the spread and infection of pathogenic bacteria spores, which greatly reduces the storage and transportation resistance of blueberries. In production, blueb...

Abstract

The invention discloses a whole-course cold-chain method for blueberries. The whole-course cold-chain method comprises steps as follows: (1), picking; (2), temporary storage: picked fresh blueberries are transported to temporary storage and refrigeration devices in various plantations; (3), transferring: the fresh blueberries stored in the temporary storage and refrigeration devices are transferred to refrigerator trucks to be transported; (4), quick pre-cooling: the fresh blueberries are transferred to a processing center through the refrigerator trucks and conveyed to a raw material pre-cooling chamber to be pre-cooled, the temperature of the raw material pre-cooling chamber is set to 5-10 DEG C, and a raw material negative-pressure pre-cooling fan is adopted during pre-cooling; (5), processing: the pre-cooled fresh blueberries are conveyed to a processing workshop to be processed and packaged; (6), pre-cooling of finished products and delivery: packaged products are put into a finished product pre-cooling chamber, a finished product negative-pressure pre-cooling fan is adopted, and the products are put into a finished product warehouse with the temperature of 0-1 DEG C after being pre-cooled and are conveyed to destinations in time. With the adoption of the whole-course cold-chain method, the temperature of the blueberries can be guaranteed, the blueberries can be packaged and delivered in 8-9 hours, and freshness and high quality of the fresh blueberries are guaranteed.

Description

technical field [0001] The invention belongs to the field of fresh fruit preservation, storage and transportation, and in particular relates to a method for the whole cold chain of blueberries. Background technique [0002] In recent years, the overall level of storage, transportation and preservation of fruits and vegetables in my country has made staged progress, and the post-harvest processing industry of fruits and vegetables has developed rapidly. It is manifested in the high loss rate of fruit and vegetable resources after harvest, and the cold chain logistics system is not perfect. [0003] Blueberry, a small berry, is blue in color, beautiful in color, covered in a layer of white fruit powder, with fine flesh and tiny seeds. The average weight of blueberry fruit is 0.5-2.5g, and the maximum weight is 5g. The edible rate is 100%. It is sweet and sour, and has a pleasant aroma. It is a good product for fresh food. In addition to conventional sugar, acid and Vc, bluebe...
