The utility model relates to a solar drying machine, comprising one or more baking containers which are used for placing the baked articles, a reflecting plate which corresponds to each backing container and is used for reflecting the sunlight and accumulating the heat in the backing containers, and a driving device which is used for driving the reflecting plate to the top of the baking containers. The solar drying machine can preset the baking temperature and the operating time, and two groups of driving devices are controlled to rotate the baking containers respectively by a controlling device. And then the reflecting plate is positioned below the baking containers to reflect and accumulate the solar energy or positioned on the top of the baking containers to prevent the sunlight from shining the heat collecting pipe continuously, and the baking temperature and the baking time are controlled.
Description
The utility model is about a kind of solar energy curer, particularly bakes and banks up with earth machine about a kind of too high solar energy of stoving temperature that can prevent automatically.
This device can be applicable to cure multiple article, as food or similar to cure the article that drying is a purpose such as fruit, is good with the tea curing that needs temperature control especially wherein.
The purpose of tea curing is stoving temperature is controlled in the proper range, to reduce the tealeaves water content and to remove tea fishy smell.In the process of curing, suitable duration and degree of heating control also can make tealeaves produce the fiery fragrance of special roasting, increases the local flavor of tealeaves.And utilize solar energy tea curing, its temperature controlling more to seem quite important, stable temperature can be promoted the stability of tea leaf quality.
The traditional tea roaster mainly can be divided into electricity roasting or charcoal griller, according to the different qualities of each equipment and tea making master worker's gimmick difference, can make with extra care out the senior tea of diverse fragrant flavour quality.Though this two method has their own characteristics each and advantage, only both all consume energy or are consuming time.
In view of this, the present utility model people utilizes solar vacuum heat-collecting pipe to develop the solar energy curing range, and application obtains No. the 111930th, the novel patent of the Republic of China in September, 1996.
This solar energy curer mainly comprises members such as solar energy heat collection pipe, electro-optical package, direct current gear motor and transmission device.The utility model is that tealeaves is directly placed pipe in the thermal-collecting tube, and the selective absorbing film that utilizes its inner layer glass appearance to be coated with absorbs solar radiation heat energy, to cure tealeaves in the pipe.
This curer will drive thermal-collecting tube by the gear motor that electro-optical package drove and rotate, and it is more even that the interior tealeaves of pipe is heated, and keeps baking quality stable.The vacuum heat-insulating layer of vacuum heat collection pipe can effectively block heat and scatter and disappear, and makes the whole process of curing more quick.What deserves to be mentioned is,, make the tealeaves that cures have traditional charcoal roasting local flavor, can improve tea economy and be worth because the selective absorbing film that is coated with on the interior tube-surface of thermal-collecting tube can discharge infrared ray.
But the temperature in the thermal-collecting tube of this curer can change with intensity of sunshine, uncontrollablely cures stoving temperature required in the process; Moreover it is also uncontrollable that it cures the time, causes the baking quality instability.
Test according to Taiwan Tea Industry improvement shows, cures 2～4 hours in 4～6 hours or 120 ℃ if cure with 100 ℃, can make tealeaves produce fragrance, subordinate's quality of tea leaves in effectively improving.And tea baking is advisable to be no more than 120 ℃, cure if surpass 150 ℃, and very easily carbonization of tealeaves, coking, the tea look transfers toward dark red, the thin and tart flavour slightly of flavour.Can find out more that thus the temperature and time parameter control has material impact to baking quality in the process of curing.
The main purpose of the utility model is to provide a kind of reflecting plate with reflected sunlight or sunshade, makes to have the solar energy heating effect, or prevents the solar energy curer that stoving temperature is too high.
The purpose of advancing of the utility model is to provide a kind of automatic control solar energy curer of controlling stoving temperature and time.
For achieving the above object, the utility model proposes a kind of solar energy curer, comprising:
One baking container is for putting the article that cured;
One reflecting plate, it is corresponding with it to be installed in this baking container limit, in order to reflected sunlight and make heat build-up in this baking container; And
One drive unit moves to above-mentioned baking container top in order to drive said reflection plate.
The utility model provides a kind of solar energy curer with reflection or sunshade usefulness reflecting plate, when temperature in the baking container reaches preset value or arrival and cures in limited time, can carry a signal to control device, use accessory drive driving reflecting plate and turn to the covering of vacuum heat collection pipe top automatically, with the irradiation of blocking sunshine, temperature continues to rise to above curing maximum temperature in the pipe to slow down.Preferably, this baking container is a solar energy heat collection pipe, especially solar vacuum heat-collecting pipe.Basically, the utility model can also turn to the baking container top by the manual operation reflecting plate.
The utility model installs reflecting plate additional outside each root solar vacuum heat-collecting pipe, and control via temperature perception controller and timer, when reflecting plate is positioned at the thermal-collecting tube below, by the reflect focalization effect of reflecting plate, can improve collecting efficiency in the vacuum heat collection pipe.When the stoving temperature in the pipe arrives preset value, order about motor via the sensing of temperature sensing controller and drive the reflecting plate counter-rotating, block sunshine with covering and continue the thermal-collecting tube that is exposed to the sun, temperature continues rising and article such as burned tealeaves in can preventing to manage.
And temperature is fallen back preset value when following again in pipe, and temperature perception controller can similarly order about motor driving reflecting plate once more, goes back to reflect the position of being exposed to the sun and heat up.Prescribe a time limit when the time of curing arrives originally predetermined curing again, timer will order about motor and drive reflecting plate counter-rotating covering thermal-collecting tube, so far promptly finish this batch and cure flow process; Unless and reset, otherwise reflecting plate will rest on covering sunshade position; Therefore reflecting plate can protect thermal-collecting tube can not broken by accidental impact further.
Reflecting plate and thermal-collecting tube divide by two different motors and drive, and the motor that drives thermal-collecting tube only is subjected to master switch control supply power, cure finish, article such as tealeaves are inclined after, master switch just cuts out.So can prevent to cure in the process,, cause tealeaves scald or burned in the pipe because of the running of thermal-collecting tube Halfway Stopping whole.Said reflection plate and thermal-collecting tube also can utilize planetary gearsets to be driven by a motor, or planetary gearsets and idle pulley are driven by motor and interactive.
The utility model can add holding storage battery in addition with outside the required power supply of solar opto-electronic board supply motor, guaranteeing power supply quality and to improve the storage utilization ratio of power supply, and can avoid control system influenced by the sunshine power, and produce interrupted wild effect.
In addition, can the arrange in pairs or groups switching acting device of general civil power (alternating current) of the utility model allows the user can reach convenience according to need, selects sunshine electric energy or general alternating current.
