Embodiment 1

[0042] When drying Ningqi No. 1, first wash and screen the fresh wolfberry fruit, and select the fresh wolfberry fruit floating on the water surface as the drying fruit; remove and drain the fresh wolfberry fruit that meets the requirements, and spread them evenly in a single layer on the fruit anvil , and then at a constant speed (to prevent the accumulation of fresh wolfberry fruits due to the vibration of the anvil, which will cause uneven heating) and transfer them to the intelligent wolfberry drying room of 10.2×3.3×2.5m. The temperature control program is set as follows:

[0043] The first stage is a slow heating period, that is, rising from normal temperature to 51°C, and the duration of heating is 3 hours;

[0044] The second stage is the first drying period, the temperature gradually rises to 60°C, the heating duration is 1 hour, and the drying time is 8 hours;

[0045] The third stage is the first slow recovery period, the temperature gradually drops to 45°C, the coo...

Embodiment 2

[0054] When Ningqi No. 7 is dried, the non-dewaxing pretreatment method and the temperature value control requirements of each temperature section are the same as in Example 1. The heating or cooling duration and holding time requirements of each temperature section are respectively: the heating duration of the slow heating period 3 hours; the heating duration of the first drying period is 1.25 hours, and the drying time is 9 hours; the cooling duration of the first cooling period is 0.4 hours, and the cooling time is 2.5 hours; the heating duration of the second drying period is 1.25 hours , drying time is 9 hours; the duration of the second cooling period is 0.4 hours, and the cooling time is 3.5 hours; the heating duration of the third drying period is 1.5 hours, and the drying time is 11 hours; the third cooling period is cooling The duration is 0.4 hours, and the recovery time is 4.5 hours; the duration of the fourth drying period is 1.5 hours, and the drying time is 11 ho...

Embodiment 3

[0056] When Ningqi No. 9 is dried, the non-dewaxing pretreatment method and the temperature value control requirements of each temperature section are the same as in Example 1. The heating or cooling duration and holding time requirements of each temperature section are respectively: the heating duration of the slow heating period 3 hours; the heating duration of the first drying period is 1.5 hours, and the drying time is 10 hours; the cooling duration of the first cooling period is 0.5 hours, and the cooling time is 3 hours; the heating duration of the second drying period is 1.5 hours , the drying time is 10 hours; the second cooling period is 0.5 hours, and the cooling time is 4 hours; the third drying period is 2 hours, and the drying time is 12 hours; the third cooling period is cooling The duration is 0.5 hours, and the slow-down time is 5 hours; the duration of the fourth drying period is 2 hours, and the drying time is 12 hours; After the period is completed, it enter...

Abstract

The invention discloses a Chinese wolfberry dewaxing-free drying technology. The technology comprises a dewaxing-free pretreatment stage, a drying stage and a shipment airing stage, and the drying stage sequentially comprises nine temperature control stages including a slow heating stage, a first drying stage, a first tempering stage, a second drying stage, a second tempering stage, a third dryingstage, a third tempering stage, a fourth drying stage and a cooling shipment stage. According to the method, dewaxing is not needed, only clear water needs to be adopted for cleaning and selecting the fresh Chinese wolfberry, the pretreatment procedure before drying is simplified, chemical agent residues during dewaxing are reduced, and under the environment without alkali liquor, ascorbic acid and other nutritional ingredients in the Chinese wolfberry can be effectively prevented from being reduced due to an acid-base reaction. Meanwhile, by adopting a scientific and reasonable sectional temperature control technology, the Chinese wolfberry is effectively prevented from being broken, the evaporation loss of nutritional ingredients such as betaine and lycium barbarum polysaccharide in theChinese wolfberry in the drying process is reduced, and the effects of functional ingredients of the dried Chinese wolfberry are enhanced.

Description

technical field [0001] The invention relates to the technical field of drying and processing of wolfberry, in particular to a technology of drying wolfberry without dewaxing. Background technique [0002] After years of development, the drying technology, method, process, and drying equipment of wolfberry have made great progress. The natural drying of goji berries has also been improved, and many plastic sheds have been developed to dry goji berries, so that the secondary pollution and weather hazards of goji berries have been controlled. Many large farms and households use hot air drying, and the drying equipment is gradually automated. Such as wolfberry multi-functional agricultural product drying room, intelligent intensive drying room, small electric heating drying room, medium-sized coal-fired drying room, large central heating drying room, box-type coal-fired drying room, intelligent intensive drying room , steam boiler central heating-goji berry drying room, etc. G...
