Described screw press includes cylindric cylinder body, piston, screw rod and pressure arm, and piston 6 is contained in the cylinder body 5, and cylinder body is contained on the fixed link 7 of base 8; The bearing bottom plate 9 of taking oilhole out of is arranged in the cylinder base, be contained in end socket 3 through screw 4 in the upper oral part of cylinder body, there is threaded hole at the end socket center; Be installed with screw rod 2 in the threaded hole; Screw rod 2 bottoms and piston are fixed together, and screw rod stretches out end socket top arm 1 is housed, described diameter of cylinder 60mm, wall thickness 3mm, high 100mm.
Technology of the present invention and equipment are simple, use easy to operate, and quality product is high; Yield is high, is particularly suitable for the preparation of the Hemp Seed oil samples that a small amount of medical and scientific research use, and the present invention tests through repeated multiple times (12 times); All obtain identical or akin result, shown that method is reliable and stable, had practicality; And the warp test has obtained fully proving that relevant testing data is following:
1. microwave heating method is squeezed Hemp Seed oil
1.1 test materials
Hemp Seed is purchased the medicinal material company in the Bozhou, Anhui, meets " Chinese pharmacopoeia standard through identifying.
1.2. experimental technique
1.2.1 take by weighing Hemp Seed medicinal material (shelling) 20g, be tiled on the suitable vessel of microwave oven, the duration and degree of heating and time are set to desired location (reference table 1), begin heating then.After heat-processed finishes, take out Hemp Seed, weighing and recording is so that calculate the moisture that loses in the heat-processed.(concrete data see Table 2)
1.2.2 fixedly squeezing condition (with Hemp Seed, be tiled in the cylinder base that diameter is 6cm, adopt the pressure of top pressurization 500Kg to continue 2min, 3 times repeatedly) is investigated the influence to milling process of application of sample amount, microwave output power, heat-up time.With the oil yield is to investigate index, adopts L
9(3
4) orthogonal table, carried out 9 experiments altogether.Level of factor is seen table 1.
Table 1 level of factor
Explain: in application, the laboratory sample amount is generally 10~20g, is 10g, 15g, three investigation levels of 20g so establish sample size; Conventional microwave oven microwave output power is 200~1000 watts, and the gear that is lower than 500W in the preliminary experiment just can make oil yield increase heat-up time more than one hour, and efficient is obviously low, so set 500W, 650W, three investigation levels of 800W; Surpass the situation that the sample over-heating possibly appear in 30min heat-up time on selected low-grade location, take into account efficiency simultaneously and consider, sets 10min, 15min, three levels of 20min.
1.2.3 Orthogonal experiment results is seen table 2.
Table 2 Hemp Seed microwave method is handled the L of Hemp Seed

4) Orthogonal experiment results
1.2.4 table 3 is seen in the Orthogonal experiment results variance analysis
The variance analysis of table 3 Orthogonal experiment results
* showing has significance
Can know that by The results of analysis of variance the influence to milling process of sample size and time has significance, can know that by the result of intuitive analysis optimum process condition is A

1C
3Oil yield is 21%.Be sample size 20g, microwave output power is 500W (2450MHz), and the time is 20min.
2. measure Hemp Seed oil iodine number, estimate the quality (content of unsaturated fatty acids) of oil
The content of unsaturated fatty acids degree of unsaturation commonly used is weighed in the grease, and greasy degree of unsaturation is represented with oil iv.So-called oil iv is meant under prescribed condition, the gram number of required iodine in the addition reaction of every 100g grease, and iodine number is high more, explains that greasy degree of unsaturation is big more, and the content of unsaturated fatty acids is high more.New expressed Hemp Seed oil is green-yellow, put for a long time then become isabelline.
The oil iv method for measuring has multiple, and wherein the iodine chloride additive process is called the Webster additive process again, and that this method has is easy, quick, accurately reach condition is easy to advantages such as control, is the most frequently used method of vegetable and animals oils determination of iodine value.
2.1. experimental principle: make the unsaturated double-bond in excessive iodine chloride (Webster liquid) and the grease carry out quantitative addition reaction:
After reacting completely, add liquor kalii iodide and remaining iodine chloride effect and separate out iodine, make indicator with the shallow lake, fixed with sodium thiosulfate standard solution, do blank test simultaneously.
Can try to achieve greasy iodine number calculation formula according to the amount of the used sodium thiosulfate standard solution of titration:
Oil iv=(V
0-V) * 1.269/m
In the formula: V
0Blank test consumes the volume of sodium thiosulfate standard solution, ml
V grease sample consumes the volume of sodium thiosulfate standard solution, ml
The gram number of the iodine that 1ml 0.1mol/L sodium thiosulfate standard solution is suitable equals 1.269
The quality of m grease sample, g
2.2. experimental section

3) after the dissolving, with newly boiling the refrigerative distilled water diluting to 1L, store in the brown bottle, place and demarcate with SRM 935a after 7 days; Webster liquid (iodine chloride glacial acetic acid solution): take by weighing 16.5 gram iodine monochlorides and be dissolved in the 1000ml glacial acetic acid, change in the brown reagent bottle and keep in Dark Place.
Sample: Hemp Seed oil
2.2.2 experimental procedure:
2.2.2.1 sample determination takes by weighing 0.1g Hemp Seed oil samples in the 500ml iodine flask with the decrement method, adds the 10ml trichloromethane, shakes gently to make the oil sample dissolving; Accurately add 25.00ml Webster liquid, the jam-pack bottle stopper, and with a small amount of potassiumiodide fluid-tight mouth; Shake up back (20 ℃ of room temperatures) reaction 60 minutes, take out along bottleneck and add 10ml 10% liquor kalii iodide, shake a little in the dark place; Behind 100ml water flushing bottle stopper and bottleneck, use 0.1molL
-1The sodium thiosulfate standard solution titration is to faint yellow, and adding 1ml 1% a starch solution continuation extremely blue disappearance just is terminal point, writes down the volume of used sodium thiosulfate standard solution.
2.2.2.2 the sample determination similarity condition is pressed in blank determination, non-refuelling appearance is operated, and writes down the volume of used sodium thiosulfate standard solution.
2.3 experiment condition and control
The amount of taking of grease sample should be confirmed based on estimating with reference to iodine number, like table 4
Table 4 Webster method is measured iodine number sample reference mass table
Annotate: the quality of sample must can guarantee that the Webster liquid of adding is excessive 50%~60%, promptly 100%~150% of absorbed dose.According to reference, this experiment Hemp Seed oil 0.1g that materialses.
2.4. experimental data and result calculate
Hypo solution calibration result: c=0.09913molL
-1(seeing table 5)
Table 5 hypo solution nominal data
Table 6 microwave method squeezing Hemp Seed oil determination data and result
Can find out intuitively that through table 6 each batch Hemp Seed oil iodine number difference is little, through statistical procedures, each batch Hemp Seed oil iodine number result's variation very little (RSD=1.6%), showing does not have difference between the numerical value.Method of proof is reliable and stable, and good suitability is arranged, and has practical value.
2.5 conclusion
Through the analysis to experimental result, definite optimised process is: raw material (Hemp Seed shells) sample size is 20g, microwave method: microwave output power is 500W (2450MHz), and be 20min heat-up time.Confirmatory experiment has shown this process stabilizing, and craft science is feasible, can satisfy the requirement that the laboratory is few with sample size, precision is high and oil yield is high, quality is good.Be that the innovation on the Hemp Seed oil is squeezed in the Hemp Seed heating.
