Problems solved by technology

[0005] However, we found that according to the methods disclosed in the prior art, for example, after freezing the roses at -30°C for 1-2 hours and then drying them, the petals of the roses become relatively brittle and shatter when touched , probably because the rose petals are thinner, and the long-term freezing makes the rose petals more brittle; in addition, we also found that the rose petals were dried according to the method disclosed in the prior art, such as using a vacuum microwave device. The partial gelatinization of the petals may be caused by the fact that the moisture formed during the drying process is not easy to discharge quickly

Embodiment 1

[0046] A kind of method adopting liquid nitrogen low temperature fixing rose shape, this method comprises the following steps:

[0047] (1) The freshly picked roses are subjected to liquid nitrogen low-temperature freezing to shape the shape, the temperature of the low-temperature freezing is -196°C, and the time is 8s.

[0048] (2) First, the frozen roses are first dried with an open blast high microwave power of 16KW for 30 seconds, then dried with an open blast low microwave power of 7KW for 3 minutes, and finally microwaved. It is 15KW open blast high microwave power drying for 40 seconds, and the wind speed during the open three-stage blast microwave drying process is 6.5 m / min.

[0049] Finally, a dry rose with good flower shape maintenance, no shrinkage of petals and beautiful appearance is obtained.

Embodiment 2

[0051] A kind of method adopting liquid nitrogen low temperature fixing rose shape, this method comprises the following steps:

[0052] (1) The freshly picked roses are first subjected to liquid nitrogen low-temperature freezing to shape the shape. The temperature of the low-temperature freezing is -196°C and the time is 5s.

[0053] (2) First, the frozen roses are first dried with an open blast high microwave power of 10KW for 1 minute, then dried with an open blast low microwave power of 8KW for 2 minutes, and finally microwaved. It is 18KW open blast high microwave power drying for 30 seconds, and the wind speed is 7 m / min during the open three-stage blast microwave drying process.

[0054] Finally, a dry rose with good flower shape maintenance, no shrinkage of petals and beautiful appearance is obtained.

Embodiment 3

[0056] A kind of method adopting liquid nitrogen low temperature fixation gardenia flower shape, this method comprises the following steps:

[0057] (1) The freshly picked gardenias were first subjected to liquid nitrogen low-temperature freezing to set the shape, the temperature of the low-temperature freezing was -196°C, and the time was 10s.

[0058] (2) The Gardenia after freezing is first carried out microwave power is 17KW open air blast high microwave power drying for 50 seconds, then carries out microwave power is 8KW open air blast low microwave power drying for 4 minutes, finally carries out microwave power drying. It is 12KW open blast high microwave power drying for 1 minute, and the wind speed during the open three-stage blast microwave drying process is 7 m / min.

[0059] Finally, the dried gardenia with good flower shape maintenance, no shrinkage of petals and beautiful appearance is obtained.

Abstract

The invention relates to a flower shape low temperature fixing method and flower shape low temperature fixing equipment by adopting liquid nitrogen. The method comprises the following steps that firstly, liquid nitrogen low-temperature freezing and shaping are carried out on fresh picked flowers, and then open type three-section air blowing microwave drying is carried out. The equipment comprisesa low-temperature shaping box used for shaping the flowers before drying, an open type air blowing microwave drying device used for drying and a collecting and storing device used for collecting the dried flowers, wherein a liquid nitrogen tank is used for conveying the liquid nitrogen to the low-temperature shaping box to form the low temperature, the low-temperature shaping box is internally provided with a supporting plate and guide rails arranged on two opposite inner side surfaces of the low-temperature shaping box, the supporting plate is arranged in the low-temperature shaping box by embedding the edge of the supporting plate into the guide rails, and holes which are uniform in shape, size and distance are formed in the bottom of the supporting plate and are used for allowing flowerstalks of the roses. According to the method, the flowers can be kept in complete flower shapes, and high commercial utilization value is achieved.

Description

technical field [0001] The present invention relates to a kind of low-temperature drying equipment and method, more particularly, relate to a kind of method and equipment that adopt liquid nitrogen to fix flower shape at low temperature. Background technique [0002] Many flowers, for example, roses are a very nutritious natural raw material, which contains a variety of trace elements, dietary fiber and essential amino acids and other nutrients. Rich rose resources and high utilization value make my country's rose industry have broad prospects for development. Roses are rich in color, and their pigments belong to polyphenolic compounds. It is a food with health effects officially approved by my country. The content of anthocyanins in roses is very high, and it has been widely used to remove free radicals in the human body and proliferate yellow leaves. Anti-tumor, anti-cancer, anti-inflammatory, inhibit lipid peroxidation and platelet aggregation, prevent diabetes, lose weig...
