The technical scheme is that a rapid moisture meter comprises a closed hot air box, a heating element arranged in the hot air box and a control system arranged on the lateral surface of the hot air box and is characterized in that the top end of the hot air box is provided with an air outlet; the air outlet is covered by a cylindrical evaporator vertical cover of which both ends are open; a metal net for supporting a heated material is arranged in an inner cavity of an evaporator; the bottom end of the hot air box is provided with at least one air inlet; the heating element is positioned between the air outlet and the air inlet; a fan which blows upwards is positioned between the heating element and the air inlet; a metal protective net is arranged at the position of the air outlet; the heating element is a positive temperature coefficient (PTC) thermosensitive ceramic heating element fixed on a ripple aluminium strip; and the outer wall of the evaporator is provided with a handle.
Description
Technical field
The utility model relates to a kind of testing tool, specifically is the instrument of measuring the moisture in the material; Especially be suitable for the determination of moisture of cereals (vegetable seeds).
Background technology
The standard law determination of moisture is that the percent of radix is represented usually with the weight in wet base, is standard with the oven dry constant weight.Its formula of mathematical is:
The baking oven volume that traditional oven drying method adopts is bigger, must be arranged in the laboratory and operate; Be equipped with electric crusher, aluminium box, glass exsiccator, electronic balance, tweeter etc.; About 1.5 kilowatts-2.4 kilowatts of baking oven power.Test a standard model and need 4-8 consuming time hour approximately (according to the different industries standard and different); Specimen need be carried out pulverization process; Complex operation can not be carried use.
The characteristics of the quick Moisture Meter of existing electronic type are that test is quick, the thing sample need not pulverized, powered battery, simple to operate is carried, adopted to the volume I.But its measurement is not really stable, and repeatability is relatively poor, especially to breed difference and high-moisture binomial index difficulty satisfy test request; Be suitable for the industry narrow range, the data that generally record value only for referencial use is used.
The utility model content
The purpose of this utility model provides a kind of moisture teller, and this analyzer should be able to overcome the deficiency of above-mentioned background technology, have test accurately fast, sample need not pulverize, convenient carrying.
The technical scheme that the utility model proposes is: a kind of quick moisture teller comprises an airtight hot bellows, the control system that is arranged on the heater element in the hot bellows and is installed in the hot bellows side; The top that it is characterized in that described hot bellows is shaped on air outlet, and the upright cover cap of the evaporator of the tubular of a both ends open aforesaid air outlet, and the inner chamber of evaporator is equipped with holding and is heated the wire netting that material is used; The bottom of described hot bellows is shaped at least one air inlet, and described heater element is between air outlet and air inlet, and other has a fan toward up-draught to be positioned between heater element and the air inlet.
Chain Link Fence is equipped with at described air outlet position.
Described heater element is the PTC thermal sensitive ceramics heater element that is fixed on the ripple aluminum strip.
Be shaped on handle on the outer wall of described evaporator.
The wire netting of described evaporator inner chamber is bowl-shape wire netting.
Principle of work of the present utility model is: start-up control system, heater element 3 and fan 2 energising work; Outside air is heated after air inlet enters, and then by passing through whole evaporator behind the air outlet 5-2, the flash-pot top end opening flows out.Being heated in the bowl-shape wire netting that material can be placed on evaporator such as vegetable seeds, taking out the balance of joining with other again through the time of setting weighs, merge input with the data of weighing before the heating, can calculate the water percentage that is heated material, and the result directly is presented on the display screen.
The utility model adopts the oven drying method principle, and adopting the oven dry constant weight equally with existing Oven Method is standard; Test a sample and only need to be in 15-20 minute constant weight (physical characteristics according to the material sample is decided); 300 watts/h-500/h of power consumption.Specimen need not pulverized, and test result is accurate, quick, reliable, and energy-saving effect is remarkable, and is safe and reliable, and the life-span is long, to not influence of environment; The PTC thermal sensitive ceramics heater element thermal resistance that adopts is little, programming rate is fast, heat exchange efficiency is high, and the adstante febre surface is not rubescent, the flames of anger, thereby material sample is not prone to the burnt phenomenon of sticking with paste in drying course; In addition, because volume little (approaching with the volume of the quick Moisture Meter of electronic type), in light weight can be carried; There are not two difficult problems of breed difference and high-moisture in the use, are suitable for industry scope wide (satisfying multiple industry moisture test request).

Embodiment
As shown in the figure, this quick moisture teller comprises an airtight hot bellows 5, the control system 1 that is arranged on the heater element 3 in the hot bellows and is installed in the hot bellows side; The top of described hot bellows is shaped on air outlet 5-2, the evaporator 6 upright cover caps of the tubular of one both ends open aforesaid air outlet, the inner chamber of evaporator is equipped with holding and is heated the wire netting 6-1 (this wire netting preferably adopts periphery high, middle low bowl-shape wire netting) that material is used.The bottom of described hot bellows is shaped at least one air inlet 5-1 and (shows 4 among the figure; Specifically can determine as required), described heater element is between air outlet and air inlet, and other has a fan 2 toward up-draught to be positioned between heater element and the air inlet, so that the hot blast that produces flows from lower to upper (shown in Fig. 3 arrow).
For guaranteeing safety, Chain Link Fence 5-3 is equipped with at described air outlet position.
Described heater element 3 is the PTC thermal sensitive ceramics heater elements (adopting PTC thermal sensitive ceramics heater element and ripple aluminum strip to form through high temperature sintering) that are fixed on the ripple aluminum strip, and buyable obtains.
In addition, scald one's hand when preventing to use, be shaped on handle 6-3 on the outer wall of described evaporator.
