Description
Technical field
The invention belongs to band shell oil plant Primary processing technology fields, and in particular to a kind of auxiliary camellia oleifera fruit shelling of radio frequency heating and
The dry method of tea seed.
Background technique
Oil tea is one of maximum woody oleiferous plants crop of China's yield, big with oil palm, olive, coconut and the referred to as world four
Woody edible oil material.Tea seed nutritive value is high, and oil content is up to 40%~55% in benevolence, wherein oleic acid and linoleic acid total content
Up to 90% or more.The oil-tea camellia husks moisture content newly harvested is 70%~80%, and tea seed moisture content is 40%~50%, in addition
The more rainy weathers in harvest season southern area need to carry out place of production camellia oleifera fruit shelling and tea seed to prevent tea seed from going mouldy in time
It is dried.Currently, camellia oleifera fruit shelling mainly has natural drying and mechanical dejacketing two ways.However, natural drying mode is imitated
Rate is low, large labor intensity；Mechanical dejacketing can substitute natural drying mode to a certain extent, but the breakage rate of tea seed
It is higher.Tea seed drying mostly uses heated-air drying mode greatly, but since tea seed seed is big, specific surface area is small, there is knot outside
The seed shell of structure densification, and the air gap can be generated in drying process between shell and tea seed, it is unfavorable for the transmitting of heat and moisture,
So that tea seed, which becomes, is difficult to dry one of oil variety, cause its hot air drying rate slow, it is ineffective.
Radio frequency (electromagnetic wave that frequency is 3kHz~300MHz) can be directed through inside material, cause material internal poles
Property molecule and the oscillation of charged ion migrate, phase mutual friction converts electrical energy into thermal energy.Radio frequency heating is for assisting camellia oleifera fruit de-
Shell mainly utilizes its volume heating effect, keeps camellia oleifera fruit inside and outside while heating up, and is evaporated rapidly using tea seed moisture inside green shell
The pressure of generation causes the rapid spalling of green shell, and green shell moisture content is higher at this time, and hardness is lower, and seed shell separation process is more easier,
Destruction will not be generated to tea seed shell.And the de- green shell of conventional heating mode (CN105942547A), heat are inside from green shell
, there is temperature gradient from the outside to the core in conduction, with a large amount of declines of green shell moisture content, green shell is shunk, and what which generated answers
Power causes green shell gradually to crack and crack, but due to hardness increase in green shell dehydration, subsequent subtractive process is easy damage
Bad oil tea seed episperm causes its storage quality to decline；Also, the process for removing oil-tea camellia husks large quantity of moisture, will also result in the energy
Waste.The hot air combined heating of radio frequency-is dry for tea seed, mainly using the heating of its volume and moisture content self-balancing effect, protects
Exhibit material thermally equivalent simultaneously in whole volume, and the higher camellia seed kernel of moisture content can absorb more RF energies, from
And guarantee that temperature is consistent with gradation of moisture direction, accelerate dry progress.Meanwhile the presence of hot wind can take away rapidly material
The moisture of surface evaporation.
