Description

A kind of method and device thereof that idesia high efficiency drying eliminates the unusual smell

Technical field

The invention belongs to agricultural product high efficiency drying technical fields, are more particularly to a kind of drying unit of idesia fruit, also It is related to a kind of method that idesia high efficiency drying eliminates the unusual smell.

Background technique

Idesia is a kind of novel woody oil resource.But since idesia has following three points defect: 1, drying is tired Difficulty is to cause drying difficult since idesia fruit epidermis covers thick wax ester；2, idesia oil has the taste similar to tung oil Road causes idesia oil to eat acceptance lower；3, fresh idesia cannot store for a long time.It, can be by as the resting period extends Gradual change is black, substantially squeezes after the idesia fruit drying of blackening not fuel-displaced.Therefore, the storage of idesia fruit is idesia processing Another key technology.

Therefore one kind drying unit that low energy consumption and drying time is short is developed for agricultural product energy conservation and environmental protection drying equipment It is of great significance.Especially for idesia, shortens drying time, removing peculiar smell, convenient for storage, be that idesia oil is processed Key link.

Summary of the invention

It is an object of the present invention in view of the above-mentioned drawbacks of the prior art, provide a kind of drying dress of idesia fruit It sets, additionally provides a kind of method that idesia high efficiency drying eliminates the unusual smell.

The purpose of the present invention is achieved through the following technical solutions:

A kind of device that idesia high efficiency drying eliminates the unusual smell, including pressure pan, the lower part of the pressure pan are provided with sieve, high The bottom of pressure tank is provided with escape pipe, and lower valve is provided on escape pipe, is provided with air inlet pipe at the top of pressure pan, in air inlet pipe It is provided with valve, is additionally provided with pressure thermometer on pressure pan.

A kind of method that idesia high efficiency drying eliminates the unusual smell, comprising the following steps:

Fresh idesia fruit is put into pressure pan by step 1, opens lower valve, the height that temperature range is 120~180 DEG C Pressure steam enters in pressure pan from air inlet pipe, after 120 degrees Celsius of temperature display of pressure thermometer, closes lower valve, Continue to be passed through high steam, until the pressure of pressure thermometer shows 2~3 atmospheric pressure, valve in closing, heat-insulation pressure keeping 10~30 minutes, then open lower valve quickly let off steam out of pressure pan, then opens valve again and leads in pressure pan Enter 120~180 degrees Celsius steam 5~after ten minutes, valve in closing, open pressure pan lid release idesia fruit；

The idesia fruit that step 1 processing obtains is put into vacuum rotary drying pot by step 2, in 60 degrees Celsius of environment Lower vacuum rotating dry 8~10 hours to get the drying idesia fruit for arriving removing peculiar smell.

Compared with the prior art, the present invention has the following beneficial effects:

1, wax is dissolved using high temperature and high pressure steam, removes the wax of idesia fruit surface, shorten ten times of drying time or more, And high temperature kills the idesia fruit after enzyme and can store for a long time at normal temperature and turns black without aoxidizing；

2, wax ester and peculiar smell are removed using high temperature and high pressure steam blasting procedure；

3, the peculiar smell of idesia fruit is promoted further to remove using vacuum tumbling.

In figure, 1- air inlet pipe；The upper valve of 2-；3- pressure thermometer；4- pressure pan；5- sieve；6- escape pipe；7- lower valve；8- Idesia fresh fruit.

Specific embodiment

For the ease of those of ordinary skill in the art understand and implement the present invention, below with reference to embodiment to the present invention make into The detailed description of one step, it should be understood that implementation example described herein is merely to illustrate and explain the present invention, and is not used to limit The fixed present invention.

Embodiment 1:

As shown in Figure 1, a kind of device that idesia high efficiency drying eliminates the unusual smell, including pressure pan 4, the lower part of the pressure pan 4 It is provided with sieve 5, the bottom of pressure pan 4 is provided with escape pipe 6, and lower valve 7 is provided on escape pipe 6, and the top of pressure pan 4 is set It is equipped with air inlet pipe 1, valve 2 is provided in air inlet pipe 1, pressure thermometer 3 is additionally provided on pressure pan 4.

A kind of method that idesia high efficiency drying eliminates the unusual smell, comprising the following steps:

Fresh idesia fruit is put into pressure pan 4 by step 1, opens lower valve 7, and temperature range is 120~180 DEG C High steam enters in pressure pan 4 from air inlet pipe 1, after 120 degrees Celsius of temperature display of pressure thermometer 3, under closing Valve 7 continues to be passed through high steam, until the pressure of pressure thermometer 3 shows 2~3 atmospheric pressure, valve 2 in closing, Heat-insulation pressure keeping 10~30 minutes, then open lower valve 7 quickly let off steam out of pressure pan 4, and it is past then to open valve 2 again Be passed through in pressure pan 4 120~180 degrees Celsius steam 5~after ten minutes, valve 2 in closing, open pressure pan 4 lid put Idesia fruit out；

The idesia fruit that step 1 processing obtains is put into vacuum rotary drying pot by step 2, in 60 degrees Celsius of environment Lower vacuum rotating dry 8~10 hours to get the drying idesia fruit for arriving removing peculiar smell.

As above treated idesia fruit can store 2~5 months and it is non-discolouring.And the crude oil squeezed out does not have not only The similar peculiar smell of tung oil, there are also a kind of fragrance that sesame is similar.

Those skilled in the art can do various repair to described specific embodiment Change or supplement or be substituted in a similar manner, however, it does not deviate from the spirit of the invention or surmounts the appended claims institute The range of definition.
