Moisture-Absorbability Of Tipping Paper And Its Influence On Machine Applicability, Liu Wenting, Cai Bing, Cheng Zhangang, Jia Weiping, Yan Aihua, Chu Wei, Wu Kai, Feng Nianjie, Wang Lei

Food and Machinery

To evaluate the moisture-absorbability of tipping paper and its influence on machine applicability, 6 types of tipping paper were used to reveal the relationship of stripping resistance and moisture-absorbability. Stripping resistance was measured by texture analyzer, and moisture-absorbability were studied by different methods including Cobb value, penetration time, contact angle and infrared spectroscopy. The results showed that the stripping resistance mainly depended on the reverse moisture-absorbability, and enhanced with its increasing. The hydrophobic coating on the tipping paper was against the absorption of water-soluble adhesive, and consequently reduced the stripping resistance.

Food and Machinery

Correlation analysis and regression analysis were used to study the correlation between cut tobacco size and main physical indexes of short cigarettes, and analyzed the specific tobacco sizes that affect the physical quality and stability of short cigarettes. Results: ① the sizes of cut tobacco which had a main influence on physical quality and stability of short cigarettes were layers X1 (>7.00 mm), X3 (3.35~5.00 mm), X5 (1.00~2.50 mm), and X6 (<1.00 mm); ② layer X1 was linearly positively correlated with the standard deviation of weight, layer X5 was linearly negatively correlated with the draw resistance, hardness and their standard deviation, there was a respectively linear negative correlation and linear positive correlation between the layer X3 and the layer X6 with the end of the amount of silk and the end of containing rate. In actual production, the physical quality of the short cigarettes and its stability could be improved by increasing the short and medium-long cut tobacco, decreasing the long and ultra-short cut tobacco according to the physical indexes with large fluctuations.

Dealing With Control Of The Farm/Ranch, Allan Vyhnalek

Cornhusker Economics

As I have traveled the state presenting farm and ranch succession/transition workshops, I’ve run into several family situations where the older generation is lucky enough to have the next generation come back to the farm. The younger generation, in some instances, is not that young anymore and have formed knowledgeable opinions about how the farm or ranch should operate. I wrote this article to challenge both the younger and older generations as they move their operation forward as a family.

Long term family cohesiveness can become challenging if there are control issues within the family. The younger generation often brings …

Investigating The Drivers Of Farm Diversification Among U.S. Fruit And Vegetable Operations, Nicholas A. Lancaster, Ariana P. Torres

Purdue University Libraries Open Access Publishing Fund

Diversification of an agricultural operation’s crop mix is considered an environmental and financial management strategy. Environmentally, crop diversification can stabilize the ecosystem via the introduction of biodiversity, allowing for more rapid response to physical and social changes. Economically, crop mix diversification can mitigate risk. Though there are environmental and economic benefits of crop diversification, little economic work has been conducted on crop diversification outside of the row crop industry. This study estimated how internal and external factors affect crop diversification among fruit and vegetable (FV) operations. External factors included access to markets and land; internal factors included farmer beliefs and …

Will “Matopiba” Change The Competitive Landscape In The International Grain Market?, Fabio Mattos

Cornhusker Economics

In a previous article in this space (on 6/20/2018), I discussed changes in the corn market and highlighted how the rapid growth of the Brazilian winter crop has been reshaping the market within Brazil and abroad. However, since corn exported by Brazil comes mainly from the country’s center-west, its competitiveness in the international market is grossly impacted by the transportation infrastructure in Brazil. The same issue applies to Brazilian soybeans as well.

The development of a new agricultural frontier in Brazil, in a region known as Matopiba, may help Brazilian grain become more competitive and bring more changes to the …

Expanding The Farm Income Safety Net, Bradley D. Lubben

Cornhusker Economics

When the 2018 Farm Bill was passed in December, producers were looking ahead to implementation and thinking of the coming decision between enrollment under the Agricultural Risk Coverage (ARC) program or the Price Loss Coverage (PLC) program. With continued low price projections at the time, the safety net decision may have seemed relatively straight-forward. Now, with all of the weather and market challenges in 2019 coupled with ad hoc assistance expected from the federal government, the safety net and the decisions related to it have become exceedingly complex. A look at the wide and expanding safety net for crop producers …
