產(chǎn)品說明：
JOYN品粗纖維測定儀是依據(jù)目前常用的酸堿消煮法消煮樣品，并進行重量測定來得到試樣的粗纖維含量的儀器。粗纖維測定儀采用濃度準(zhǔn)確的酸和堿，在特定條件下消煮樣品，再用乙醇除去可溶物質(zhì)，經(jīng)高溫灼燒后扣除礦物質(zhì)的量，所含量稱粗纖維。粗纖維測定儀不是個確切的化學(xué)實體，只是在強制規(guī)定的條件下測出的概略成份，其中以纖維素為主，還有少量半纖維素和木質(zhì)素。
產(chǎn)品特點：
1、粗纖維測定儀消煮裝置采用陶瓷加熱材料，熱效能好，能充分獲得消化效果。
2、所有浸提過程可通過自動放置閥操作，每個樣品整套試驗可單獨操作。
3、內(nèi)置蠕動泵,耐腐蝕，可氣體反吹，加速洗滌效果。
4、粗纖維測定儀可配循環(huán)恒溫水浴，進行高精度溫度控制。
5、樣品高度可升調(diào)節(jié)，方便取樣放料。

Product description:
JOYN brａnd crude fiber tester is based on the currently used acid and alkali digestion method to boil the sample, and carry out weight measurement to obtain the crude fiber content of the sample. Crude fiber tester adopts acid and alkali with accurate concentration to eliminate boiled samples under specific conditions, and then USES ethanol to remove soluble substances, after being burned at high temperature, the amount of mineral is deducted, and the content is called crude fiber. The crude fibre tester is not an exact chemical entity, but is an overview of the components, mainly cellulose, with a small amount of hemicellulose and lignin, under generally accepted mandatory conditions.
Product features:
1. The crude fiber meter is made of high-quality ceramic heating materials, which has good thermal efficiency and can fully obtain the digestion effect.
2. All extraction processes can be operated through automatic valve placement, and each sample set can be operated separately.
3. Built-in inlet peristaltic pump is resistant to corrosion and can be blowback to accelerate the washing effect.
4. The crude fiber meter can be equipped with a circulating constant temperature water bath for high-precision temperature control.
5. The sample height can be upgraded and adjusted to facilitate sampling and discharging.
Technical parameters:
Crude fibre tester model: JOYN-CXW-6
Test object: the content of crude fiber in all kinds of grain, feed, grain, food and other agricultural and sideline products
Number of test samples: 6 / time
Repeatability error: crude fiber content is below 10%, absolute value error is not more than 0.4
The crude fiber content is more than 10%, and the relative error is less than 4%
Test time: about 90min on the instrument (including 30 minutes of acid, 30 minutes of alkali, about 30 minutes of filtration and washing)
Power supply: AC220V / 50 hz
Power: 3.3 KVA
Size: 540 * 450 * 670 mm
Weight of crude fibre tester: 28kg
