Problems solved by technology

However, due to the short harvest period of roses and the concentrated production of flowers, they cannot be processed in time. In industry, the salting method is generally used to store roses. The roses are salted and stored with 25% of the weight of flowers, and they can be preserved for 60-90 days. No deterioration, but this method will cause a serious loss of aroma after salting the flowers, and the quality of processed products such as rose essential oil and pure dew will decline, and the salted waste liquid contains a large amount of salt, which will cause serious environmental pollution when discharged into the natural environment

Embodiment 1

[0036] A method for freezing fresh roses, comprising the following steps:

[0037] 1) Picking: picking half-opened roses in the shape of a wine glass before sunrise;

[0038] 2) Pre-cooling: Within 2 hours after the roses are harvested, send the picked roses to an air-conditioned room at 8°C in time, and spread them to cool for 3 hours to prevent the flowers from being covered by the flowers after they are packed. It can reduce the water content of flowers;

[0039] 3) Packing: put the above-mentioned pre-cooled roses into foam boxes. Mix and place 9 bags of food-grade desiccant silica gel with 3g in each bag. The desiccant is packaged in non-woven fabric, and 2 frozen bio-ice bags are placed in the center of the foam box; the box must be filled with flowers, which can neither be compacted nor leave extra space;

[0040] 4) Sealing: After the packing is completed, cover the box cover and seal the foam box with adhesive tape;

[0041] 5) Quick freezing: Immediately send the...

Embodiment 2

[0045] A method for freezing fresh roses, comprising the following steps:

[0046] 1) Picking: picking half-opened roses in the shape of a wine glass before sunrise;

[0047] 2) Pre-cooling: Within 2 hours after the roses are harvested, send the picked roses to an air-conditioned room at 10°C in time, and spread them to cool and pre-cool for 2 hours to prevent the flowers from being covered by flowers after packing them in a high temperature. It can reduce the water content of flowers;

[0048] 3) Packing: Put the above-mentioned pre-cooled roses into a foam box, the size of the foam box is length×width×height=50×40×30cm, and the amount of flowers in each foam box is 7kg; the roses in the foam box Mix and place 14 bags of food-grade desiccant activated alumina with 5g in each bag. The desiccant is packaged in non-woven fabric, and 4 frozen bio-ice bags are placed in the center of the foam box; the box must be filled with fresh flowers, which cannot be compressed In fact, no ...

Embodiment 3

[0054] A method for freezing fresh roses, comprising the following steps:

[0055] 1) Picking: picking half-opened roses in the shape of a wine glass before sunrise;

[0056] 2) Pre-cooling: Within 2 hours after the roses are harvested, send the picked roses to an air-conditioned room at 8°C in time, and spread them to cool and pre-cool for 2.5 hours, so as to prevent the flowers from being covered by the flower temperature after packing, and It can reduce the water content of flowers;

[0057] 3) Packing: Put the above-mentioned pre-cooled roses into a foam box, the size of the foam box is length × width × height = 45 × 40 × 50cm, and the amount of flowers in each foam box is 10kg; the roses in the foam box Mix and place 15 bags of food-grade desiccant silica gel with 5g in each bag, packed with non-woven fabric, and put 2 layers in the foam box, and place 3 frozen biological ice bags at an interval of 20cm between each layer; the box must be filled with flowers , neither c...

Abstract

The invention discloses a method for freezing storage of fresh rose flowers. The method comprises 1) picking: picking fresh rose flowers before sunrise, 2) precooling: timely feeding the picked rose flowers into an air-conditioned room at a temperature of 8-10 DEG C and carrying out spreading pre-cooling for 2-3h, 3) encasement: putting the pre-cooled rose flowers into a foam box, mixing the rose flowers and a food-grade desiccant in the foam box, putting 2-4 frozen biological ice packs in the foam box at height spaces of 20-25cm, 4) sealing: sealing the foam box after encasement, 5) quick-freezing: immediately feeding the sealed foam box into a refrigeration house, and carrying out freezing at a temperature of -20 DEG C, and 6) freezing storage: carrying out freezing storage on the quick-frozen rose flowers at a temperature of -5 to 0 DEG C. The method changes the salted storage method of the rose flower, uses the quick freezing and freezing storage technology to make the rose flower in the dormant state and delays the cell physiological activity so that the freshness preservation is realized. After storage for 60 days, the flowers still retain original color, aroma and quality.

Description

technical field [0001] The invention relates to the field of storage and preservation of fresh flowers, in particular to a method for freezing fresh flowers of roses. Background technique [0002] Rose flowers are raw materials for extracting rose essential oil, pure dew and processed flower sauce. In the aroma industry, rose flower processed products have attracted more and more attention and attention, and the market share of rose essential oil and pure dew has increased day by day. However, due to the short harvest period of roses and the concentrated production of flowers, they cannot be processed in time. In industry, the salting method is generally used to store roses. The roses are salted and stored with 25% of the weight of flowers, and they can be preserved for 60-90 days. No deterioration, but this method will cause a serious loss of aroma after salting the flowers, and the quality of processed products such as rose essential oil and pure dew will decline, and the ...
