Shopping for espresso equipment from Internet sites can befrustrating. There are lots of options to choose from and manyadvertised performance metrics lack intuitive value (for example, motorRPM). To make matters worse, semi-anonymous consumer reviews vary inquality and objectivity, and it's not uncommon that some reviewers"shill" by placing positive evaluations of products theywish to promote. Although most fraudulent reviews are easily recognizedby their unqualified glowing assessment that is inconsistent with otherreviewers' experiences, it makes for tedious and time consumingresearch.
To round out this review and give you a defense against potentialmarket hype, I'll begin by defining some commonly advertiseddistinctions between grinders; I've ordered them from the mostintuitive to the least obvious:
Home baristas regularly debate the merits ofdoser and doserless grinders. Arguably a doser is never used for its intended purposein a home environment (i.e., measuring out a predetermined amount of coffee) because the chambermust be at least half-full so the weight of the grinds is sufficient to accuratelyfill the "pie wedges" formed by the doser vanes. Instead the doseracts as a staging area for the grinds exiting the chute and the vanes simply push them towards the drop hole at the front of the grinderinto your awaiting portafilter.
However, the doser isn't entirely superfluous. If you've ever attended a barista competition, the frenetic "thwack thwack thwack" of the doser handle almost blurs into a continuous buzz.One explanation for the baristas' behavior, besides nervous energy and way too much caffeine, is that the advancing of the doser vanes helps agitate the grinds exiting the chute. Baristas using a doserless grinder cannot "mix things up" until the grounds reach the portafilter. As a quick comparison of the visual difference, see the two loosely filled baskets pictured above. The surface of the grinds dosed "competition style" on the left appear free of clumps compared to the grinds from the doserless model. However, whether this added mixing is consequential is questionable, and I didn't note an in-cup difference given a well-practiced dose-distribution-tamp.
Some espresso purists insist one should only change the grind tocorrect a too fast or too slow pour. I believe you'll have betterresults by watching the pour instead of a stopwatch. Regardless, giventhe emphasis on precise 25 second pulls that dominates online discussionboards,it is worth noting several techniques for those who wish to compensatefor small differences in pour times between two of the Macap'ssteps:
This is the straightforward way of dealing with it: Put the timer inthe drawer, watch the stream color and cut off the shot when it blonds.If it isn't widely off mark time-wise (i.e., less than 22 secondsor greater than 32), it is close enough. In other words, let your tastebe the judge and "Trust the Force, Luke."
If changing the tamp pressure from shot-to-shot offends, insteadincrease the tamp pressure for all shots. The "hardtamping" barista sees a smaller pour time change between twoincrements than a "light tamping" barista.
The principle advantage of an incremental adjustment is the ease of re-finding widely spaced settings, which appeals tothose who frequently change between different types of coffee preparations.The Mazzer Mini is certainly capable of moving quickly between espresso and French press grind settings, althoughit requires a firm two-handed grip. The worm drives of the Cimbali Junior and Macap M4 Stepless are ideally suitedfor minute adjustments of a dedicated espresso grinder.
The Tetra Pak Ingredient Doser M3 is a unit designed for continuous and accurate injection of additional ingredients into ice cream products and other liquid and viscous products.
Capacity:
The doser handles ice cream products - and other liquid and viscous products - with added fruit pieces, nuts, candies and more. The 3000 model also handles inclusions such as cookie dough and whole biscuits.
The hopper lid opens backwards, enabling ingredients to be added from the sides and front at a low re-feeding height. This provides easy access for operators to refill the hopper if required. Two dosers may be placed beside one another without obstructing the refill process.
As the auger turns, the ingredients are transferred at a steady dosing rate from the hopper to the pump. This unit can be fitted with a variety of different augers, and they are easy to change. This means your dosing is always optimized for the product type, size and required capacity range.
Ingredients are fed into the lamella pump and the cavities between the lamellas carry the inclusions into the pressurized product zone. The pump is designed to transfer the ingredients gently into the pressurized base product, without breaking or damaging them, and without incorporating any air into the mixture.
The lamellas are designed with ventilation holes to ensure that all the air is released from large inclusions such as cookies, which may have a lot of trapped air inside them. When the pressurized base product meets the cavity, it naturally replaces any air that may be present between the inclusions, and that air then escapes through the ventilation holes.
Placed on top of the hopper, the magnetic grid is designed to trap any foreign objects made of metal, which may have found their way into the ingredients packages. Although this is a rare occurrence, an error can have dramatic consequences, so it is worth safeguarding your production with this simple option.
Background and Aim: Frequent blood glucose (BG) monitoring and insulin administration are necessary in intensive insulin regimes. A new integrated system, InDuo is a compact and portable combined insulin doser and BG monitor, designed to overcome some of the limitations of current insulin therapy. The aim of the study was to compare InDuo and a non-integrated system (HumaPen Ergo and Accu-Chek Sensor Meter) for efficacy and safety, and to evaluate patients preference. Materials and Methods: The trial design was a multicentre, randomised, 12-week, open-label, comparative, two period crossover. One hundred and ten patients with diabetes, treated with a basal bolus regime, were included. The subjects were assigned to use either InDuo or the non-integrated system. After six weeks of treatment, the subjects were transferred to the alternative system. To assess efficacy, fasting plasma glucose (FBG), 7-point blood glucose profile, serum fructosamine and HbA1c were measured. Serum fructosamine and FBG were measured at baseline and at six and 12 weeks; HbA1c was measured at baseline and week 12. Safety endpoints were number and severity of hypoglycaemic episodes, adverse events and adverse device effects. Patient preference was assessed by a comparative device questionnaire at 12 weeks. Results: Analysis with an ANOVA mixed model showed no difference after each treatment between serum fructosamine or between FBG levels. HbA1c decreased during the trial from 7.5 % 1.2 to 7.1 % 0.8 at 12 weeks. The safety profiles were similar for both treatments for hypoglycaemic episodes. The incidence of adverse events was also similar. There were 10 adverse device effects reported: eight for the Innovo device in the InDuo, one for the InDuo device and one for the Accu-Chek Sensor Meter. The comparative device questionnaire at 12 weeks showed patients strongly preferred InDuo to HumaPen Ergo and Accu-Chek Sensor Meter (all p < 0.0001). Of those preferring InDuo, more than 60 % classified their choice as very or extremely strong. Both memory functions in InDuo (i. e., for insulin dosage and for blood glucose readings) were used by more than 70 % of the patients. Conclusion: Treatment with the InDuo system was as effective and safe as treatment with the non-integrated system. Almost 75 % preferred using InDuo to the non-integrated HumanPen Ergo and Accu-Chek Sensor Meter.
The committee was formed in June following national and local protests against racial injustice. The town hall on Wednesday allowed University of Iowa students, staff and employees anonymity and feedback on how the campus can be safe for everyone, especially BIPOC and marginalized groups.
Attendees at the town hall split up into groups of about 15 people, where facilitators presented three different prototypes for campus safety models. After each prototype was presented, people were able to give feedback either verbally or anonymously through Mural.
The first prototype presented in video/PowerPoint format was centered around refocusing and retraining campus police forces and the UI police department along with adding a new wellness division within the department. The model focuses on identifying the difference between safety threats and criminal activity with crises and mental health incidents.
In another anonymous mural board, people in the breakout room were asked to give their initial reaction to the prototype, as well as the most and least effective parts of it and suggestions for modifications.
The model calls for the president to create a cabinet member to serve as an administrative liaison for the oversight committee in its reviewal processes. Member requirements for the committee would include having background knowledge of justice and equity. Ideas include housing this committee within the Diversity, Equity, and Inclusion Division at the UI.
The final prototype emphasized a holistic approach to campus safety. This model uses mental health professionals and trained mediators and minimizes the role of police officers as an effort to empower community and campus resources as primary responders and sources of safety.
The model would create a new structure, a Central Campus Support and Safety Center, designed to serve members of the UI community in any well being and safety needs they might have. The plan intends to minimize situations that police officers respond to on campus and increase the presence of social workers and mental health professionals. It would also include a partnership with a local community crisis response team where trained mental health professionals would address and respond to issues instead of police.
